@@abuzakirnaik142 Yes. Because evolution created us. In proportion with our complexity our intelligence is so high that some people create made up mythical creatures. However 95% are incorrigible to learn the truth.
We were in a car accident when my daughter was 5 years old, the broken window cut the back of her hand wide open. When the hand surgeon came to the Emergency Room, the doctor and nurse kept trying to block her vision of her hand. When she finally got past them, her response was to say “Wow! Look at that, you can tell how my whole hand works!” The doctor told the nurse it was Ok. My daughter became a doctor.
I gotta admit, I didn’t think this would give me chills, but when you first turned the cadaver to show the palm and the rest of the fingertips, I got a big shiver! I’m gonna keep watching, though, it’s too interesting to stop.
Is it only me or others also think that these videos teaches us self love ? I stare my hands and make wieard movements and see how many things are moving in it . I love the complexity of my own body.
Same here. I stared at my hands, and thanked them in my mind. I realized I don’t really appreciate my hands enough because I’m used to them being just here, but I can never imagine life without my hands. I’ll be extra careful and appreciative of them from now on, thanks to this vid. 🥺
ah i agree with you so much, self love 100%. not just the hands obviously, im slowly able to feel more confortable in my skin now knowing properly how there are so many amazing things happening inside it..
When I see how complex our bodies and DNA are, which are made from cheap organic materials that will eventually turn to dust, I get this strange feeling that the evolutionary process is a SCAM! There's just NO WAY a creative designer was not responsible for us being here! Of course that raises another 1,000 questions to answer! Where's my dusty Bible??
i too agree, i was studying about the human immune system i was curious about how it works and i wanted more info about it, but after i got the proper information i realised that the immune system is so wonderful! i was so grateful that i had a good immune system and i was healthy, the fact that those guys sacrifice thier lives so that you get to live another day made me so grateful of it, and made me take care of myself and eat proper food to make them live for more time, and after i see these types of videos it just makes me appreciate how complex and wonderful our body is. Last thing before i end this comment, dont take any simple thing about your body for granted cause without it, your lives will be much tougher :)
I am an artist, so I am fascinated by the human hand because it's one of the most difficult parts of human anatomy to draw accurately. It has such a huge variation in positions that it's very easy to draw these positions wrong. Studying hands is essential for all artists. Thank you for sharing all this info!
I'm here as an artist aswell. Looking to understand the machinations of the hand to create a moving skeletal hand sculpture. If you're looking to get to grips (pun intended) with understanding how to draw anatomy I can't recommend the Burne Hogarth Dynamic anatomy series enough. Or any book by them tbh. They have ones on hands, faces, the body, dynamic lighting and shadows and wrinkles and drapery. I think they're quintessential for anyone looking to draw the human body
When you made that disclaimer that fingers and hands upset some people, I didn't think much of it. But when I actually saw the hand it sent chills down my spine. It truly is different than other cadaver demonstrations because it is so personal and relatable and seeing it disconnected from the body and moved around is very uncanny.
Several years ago a concrete block fell on the tip of my left ring finger and smashed it almost completely off. I was wearing artificial nails at the time which may have saved the finger. At the hospital the doctor said it was like a tube of toothpaste. He called it a burst fracture and the the bone was essentially powdered. It wasn't until the following day that I realized the finger next to it was also broken. There was a chance that the finger would have to be amputated (also a chance that the finger would continue to fracture down). It didn't. He said eventually the bone fragments would find their way back together and form a lump of bone and knit back together; not the way they were but in some form. I guess it was true. My finger is malformed but unless you look at it you don't notice there is anything wrong. The nail has grown back completely normally. You do see a strange looking bone on the x-ray.
My right hand ring finger nail was cut from the middle. The previous day actually my finger got snapped by the car door. It did hurt alot but nothing was visible maybe because it was nighttime and to this day my nail grows in the same way, cut from the middle.
I'm not so sure about that statement. Your skin rests against the finger bone and the nail is on the other side of that bone. No pressure is applied to the nail when you are gripping something. Unless you are gripping with just the fingertips, which isn't the usual way to pick something up.
@@chachacamel actually, he's very much correct. Just do your own demonstration. Close your eyes if you need to. Slowly grip some thing with your fingers, although you will notice the sensation of touch initially with inner part of your finger. Concentrate a little further and you can feel the pressure build at the outside of the finger or at the underside of the finger nail. How it seems to work is this (although you are correct about the bone providing resistance) : as you squeeze something the fatty tissue on the underside of the finger is displaced outward and upward, some of it directly to the bone, but the rest of it is displaced around the bone. With the fingernail on the opposite side the skin and fatty tissue meet further resistance creating more pressure and improving contact area at the underside of the tip, hence improving grip. You are also correct that this function is maximized when using just the tip. That in it self proves much of the theory. And that function, using the very tips of our fingers is a very special trait that we have.
@@chachacamel Your flesh, like everything else, will take the path of least resistance. When your fingertips apply pressure, the least resistance would be to go to the other side of the bone. The fingernails are little barriers to impede that movement, providing resistance for the flesh when it tries to move. This allows better grips and keeps more flesh there to cushion the bone. Play around with poking different parts of the fingers, you'll observe this behavior.
The fact that the arm in the video was actually a person who lived , prolly helped his/her kids take his/her first steps ! Thankful to people who actually donate themselves to medicine !
@@leox8279 probably used for study before and after the video. Also, the video itself is education, therefor is technically a scientific study for anyone watching. The body was still donated to science/medicine.
Just remember that those bodies that were "donated to science" may not always be a choice. Sometimes, patients die but their family could not afford to pay the bills to give the person a proper funeral, hence, they're forced to donate them.
I didn't expect it even after the disclaimer, but I gasped a little when I saw those fingertips. But then I just felt amazed and thankful to the person who, in a sense, lives on as a vehicle to teach others what we have to be so grateful for. Thanks for this excellent video, you are an incredible teacher and this is a really valuable thing you do here on RUclips!!🙌
Professor, obrigado pela aula. Terei que assistir no mínimo umas três vezes para entende-la completamente devido à língua inglesa, mas o que mais me chamou a atenção foi sua capacidade de ir além da anatomia "basica", comentando sobre as funções, evolução, etc.
For some reason, the anatomy of the hand was one of the most interesting parts of cadaver lab when I was in school…apart from the brain and heart of course.
Ohhh I see why finger tips and nails can freak people out now - they look completely different to the other preserved tissue so you've got very alive-human looking finger tips on a comparatively odd looking rest of the arm... almost like an arm that's got in quite a severe accident 😬
I’ve learned so much from this channel and have been binge watching your episodes. I had a thorn in my elbow for about 14 years and wondered my I never got any major nerve or muscle damage and these videos just gives me insight on how the body works.
I have to HAND it to You, that was a pretty good pun . All joking aside , You are right in saying that the cadaver arm /hand is beautiful and not scary . Seeing such astounding beauty and complexity surely makes me take nothing about how my Body is constructed for granted . I was not "grossed out " or "scared" . Being deeply spiritual , I was in awe when seeing this Video. Nature is AMAZING and the Creator is ENDLESS in Power, Majesty and Glory .
a name and personality? really? i didn't think THAT many people gave their hands such thought..i thought i was little quirkier than that having two physical (left/right) personalities 😸🙈
Watching this with extreme interest 4 hours after surgery on my hand and wrist after a motorcycle accident. Thank you for helping me understand the mechanism of my injury more in depth after watching this video!
One day I was pruning a large branch, with large pruners. I put a lot of force on them with my hand. The next day, I could not move my right finger and it took a year to completely heal. Seeing this video, I was able to see that there are two ligaments, (at least) connecting to that finger: one flatter looking one along the top and one UNDERNEATH, inside the palm. That explains SO MUCH and now I see how the handle of the pruning shears, pressing in the palm of my hand, could easily damage that delicate ligament, with enough pressure on it. THANK YOU for this very descriptive video!! I learned SO MUCH!!
I love the way you can see the GENUINE excitement on this fellas face as he speaks. How awesome he ended up with a career which was so fufilling to his interests and skills Thank you for teaching us brother!
Truly fascinating. As a professional pianist with well over 20,000 hours of playing behind me. This is amazing to watch and the number of muscles behind the work we do as musicians is just staggering. To think that all these do everything I need them to do at the piano is almost all done automatically is mind blowing. Thanks for sharing.
We are wonderfully and fearfully made! The complexity shows a clear designer who put us together! I have A huge W scar on my left wrist and hand from surgery after my wrist was broken in a fall. The surgeon must have been really skilled to navigate and repair that area!
What is also really amazing is the touch sensitivity of the fingertips. They can measure exactly how much pressure the hand and fingers should apply for a good grip. My dear Wife lost that sensitivity in two fingers and she keeps dropping stuff just because she cannot feel the grip!
really? thats pretty cool, ngl i knew abt the sensitivity as theres many touch receptors in the fingertips, but i didn't know abt the measuring pressure of held objects
Finally, my morbid curiosity has been satiated 😂 Ever since you mentioned that cadavers' fingertips gross people off, I've been curious to see what they really look like
Same! I actually found a few vids where the hands weren't covered up and just thought people are weird. It doesn't phase me at all. I enjoy this type of content and I'm not easily grossed out. But yeah the uterus they found on the old lady cadaver had her hands exposed
I remember not being overly sensitive to the cadavers in the lab until I saw one lady with hands/fingers like my mom's that still had fingernail polish on. It's amazing how polish survived all the embalming fluids. My mom had passed away the same year which is why it bothered me.
3:40 I broke my thumb after a motorcycle accident recently and had to have it in a cast for a month, even though I had completely free movement of the remaining 4 fingers I couldn't believe how many simple tasks I couldn't perform without struggling or help from my other hand, thumbs are underrated!
When I saw those fingertips, I couldn't help but wonder at the fact that they belonged to a person who had to have atleast lived to their twentys and probably further. I kept wondering if those fingertips once carressed a child's cheek, once held a lover's hand tight, once gripped the bar of a rollercoaster, and so on. These kinds of videos really put being a living creature made of meat in to perspective.
In another video they explained where they got their cadavers and what information they get provided. They know very little: only the name, age and cause of death, if I remember correctly. The cadavers were definetely 60+ and mostly around 70 or 80 years old. One cadaver, maybe this one even, was from a lady who died of natural causes around 90+ years old :)
The human body really is just amazing. My mom had an accident last year, she fell into our empty pool while we were emptying it to clean it, and broke both of her wrists, her right shoulder, and her left foot. She had surgery twice on the right wrist but the left one was relatively okay, though both still give her pain and slight difficulty moving. She can't make a complete fist and her thumbs aren't as flexible as they were before. She also has some numbness in her right arm, starting from her mid-forearm and going down her pinky and ring finger, so we think one of her nerves was damaged too. Obviously this has been really difficult and tragic, and I've done my best to take care of her and keep her pain at a minimum/advocate for her medically. But I also can't help but think that the hands and wrists are just so cool and our bodies are so resilient. (And, of course, I'm really grateful my mom survived the fall and her injuries weren't as severe as her neck or spine breaking!)
I got a distal radius fracture in my right wrist, and also fractured my scaphoid and damaged some of my wrist tendons in a snowboarding accident last winter. Recovered now but after watching this its clear to see why my entire hand and upper forearm was also affected as a result. Crazy how many muscles and different tendons work together to move your hand and wrist. These videos are very informative and fun to watch, thanks for teaching all of us!
Half the time (mostly during tendons & ligaments part) I was reimagining/remembering muscle vein & bone anatomy posters/images I've seen so many times. Those few main nerves, like with veins, going to the hand (like in feet) then branching out in so many... like small channels (rivers) or small then tiny roots.
Thank you professor, it's a major task for artists to depict hands, and it's incredible how the human body works!! Everyone at this channel is so good at teaching, that I always get fascinated at the videos!! Thank you for sharing your knowledge with everyone!!! ❤
I had a disk on a high speed grinder explode and it destroyed a good part of my left hand. Through many surgeries over a few years I have regained reasonable use of the hand again. One aspect that amazes me is how parts of our body sort of regenerates. I was missing a silver dollar sized chunk of flesh in the palm just under my little finger and ring finger. Although the surgeons transplanted veins to replace arteries, tendons and nerves, they opted to just leave that chunk of skin and flesh open to heal on its own. Although it took nearly a year, not only did the skin grow back over that area but the same palmer creases appeared as well as the same ‘fingerprints’ formed anew in the missing area. I just found it interesting that missing chunk grew back. Now if I could just get that dang little finger to move when I want it to and not decide to move when I don’t expect it to move!
I totally agree with you-the only time it bothered me in the anatomy lab was when I saw an older woman with her fingernails painted. I started thinking about her life and that someone cared enough to paint her nails. I had to walk out and cry a little before I could return and I hardly ever cry.
I fell over last week and sprained my thumb, it’s fascinating to see the structures of the hand while gently probing the parts that are tender and seeing the affected areas :)
Seeing you handle those big nerves in the forearm made me think of Aron Ralston who had to amputate his own arm to free himself. He said cutting through those nerves felt like sticking his arm in hot magma.
It's truly amazing how complex our hands are, especially when playing musical instruments with them. Though it would be neat to see you guys cover the insane complexity of the human feet. I'm sure many barefooters (and organists) would love to see your take on them, especially with the barefoot movement growing a lot over the years.
I think playing musical instruments speaks more of our abilities of memory and the brain rather than the hand. Unless you are playing your instrument very fast.
@@dominikweber4305 because most musicians play with muscle memory and only need to learn how to play at the first time. And that learning mostly is about forming memories of the right way to play. :)
@@manumusicmist i know, i play the guitar. I think the original commenter was speaking of the actual physical complexity that is needed to move your hands in such nuanced ways
Very interesting. I’m recovering from having broken my left wrist and forearm into 15 pieces. It has 3 pins and a cast and at this time it is no help to the right hand. It’s amazing how much one useful hand feels lost without the other other.
I remember when my girlfriend was studying anatomy in med school. When she was working on the cadavers arms she could not eat chicken legs for a year or so. Me being a lover of dark meat and going to school to be an electronics engineer happily took the legs.
I had the same feeling watching this video! That human arm/hand looks like a chicken leg, and we eat chicken legs.. so almost like someone would eat human arm/hand? Brrr I know its abstraction but gave me chills. No chicken legs for me too for a while!
Would love to see a follow up video of the pulleys, and boney structures that work to make the actual motions of the hand, pivoting surfaces and joint capsules! Awesome video! Studied the hand specifically for over six months for a project in mechanical engineering! Its a fascinating topic!!
The human body is such a work of art in every single way. The way everything in it works together so very well, everything having a purpose to help sustain a life. So amazing, sometimes I wish I had taken a profession in the field.
@@davidarcher3386 It is evoluiion, whether you like it or not. Not likimg something doesn;t change that fact. Also, it blows my mind that in the 21st century people still believe in a fairy tale about a sky daddy. Grow up you daft sod.
Love, love, love this video. Thanks! As a robotics designer wannabe, attempting to approximate the complexity of the human hand is DAUNTING, to say the least. I appreciate and love all the work that Nature put into developing the hand (muscles, tendons, bones, ligaments, nerves) and the brain (to control this "output" device as well as interpret sensory data, i.e. "input"). "Simply" fascinating. THANKS, so much! I want moarrrr!!!!
I cut my hand almost completely off about two years ago, made me realize how complex the hand is when the surgeon explained putting it all back together. Only thing I didn’t cut through was my palm skin an pinky finger area
@Ziplokk yes indeed...piano..guitar..holing a microphone..pressing the buttons in on a saxaphone...holding drum sticks... hands are pretty clever parts of the body x
@Ziplokk Yes you are quite right, i dont play sax but can only imagine to what extent the hand and fingers are required for that...I play guitar and keyboard but my main use for my hands musicaly is a microphone, so my hand muscles are not needed as much as yours are he he , i hope you have a great weekend and i enjoyed reading your comment this morning, nice start to my day, take care x
@Nombre Apellido I'm thinking of Tony Lommi of Black Sabbath. While working at a metal sheet factory, Tony lost the tips of his right-hand middle and ring fingers, which made fretting the guitar impossible. He first tried playing the guitar with his right hand - but when that didn’t work, he first molded plastic tips to protect his fingers and re-adapted his technique. Then, as bending strings was tough on him, he also tuned down his guitar, going from E to C# - and so, the down-tuned, heavy metal guitar sound was born. Pretty amazing.
Like the hand, eye is also said to be an extremely complex organ. Can you please make a video on that one too, if its possible? It would be really fascinating to see how the eye, beyond our common knowledge, works.
It’s interesting how similar the overall structure is to other animals. The front shanks of a deer, for example, are the equivalent of our forearms. I want to know how diabetes damages blood vessels and nerves. I have severe neuropathy and peripheral circulatory damage from it. Can diabetes cause actual brain damage?
Im a medical student but bcoz of corona virus my university isn't calling us back and now it's my 4th semester online , without lab . Thank u so much for making these videos this really helps me to understand anatomy much better and gives me some satisfaction about this subject ❤️
Excellent high quality and explanation as usual. Thanks for the brief evolutionary recap at the end. And all of these for free on RUclips! Good work, guys.
i find it so interesting that our body just takes care of itself. it's so many different things that just complement each other. it's so cool i can't even describe it
Some weeks ago, I had flexor tendon repair surgery with some complications. This video made me understand my surgeon's thought process while repairing my pinky tendon. He explained but looking at a real hand I now get why he proceeded the way he did. Everything regarding hands is too complex to take lightly, but simultaneously it is truly mesmerizing.
As a OT with the specialization on hand, this was fascinating to watch. Took me right back to our anatomy classes where we had to prepare cadavers and differentiate between the different ligaments, nerves, muscles and how many things can go wrong. We mainly had the focus on different illnesses, deformities and diseases, and how they affect the hand. We rarely had a physiological opportunity to see and prepare. Did you by chance already made a video about m.dupuytren? I still try to find a way to make it more understandable for clients.
I was in the high school library one day and saw a book titled "Hands" or "The Human Hand" or something like that, not sure what exactly... I read a few pages, mostly looked at the pictures, just showing diagrams of the human hand, the bones, all the muscles, tendons, etc. and it has fascinated me ever since then. Sometimes when in boredom I just look at my own hand and wiggle my fingers just to see all the things moving around. I have such skinny hands that I can even see the veins moving around as I move my fingers. It really freaked out my classmates when I did this lol
This was amazing! A little weirded out by the hand, but not as bad as I thought! Would love to go more in depth on the hand and all of the structures and how they interact with eachother! Keep it up guys!!
about what he says on fingerprints: I have noticed this as well. I do a lot of rock climbing, and sometimes my fingerprints get pretty well worn off. I can still grip the rock just fine, but it makes it hard to fell different texture nuances without them. and touch id never works haha!
The mechanics of a finger nail make so much sense, I have busted my nail bed from jamming it between a 80 pound dumbbell on the bottom rack as the nail was falling off it would partially open like a trap door when I grab things 💀
Fun fact: the thumb is so important that for the people who lose it, the doctors amputate one of the big toes and make it become the new thumb. Saw it on a man's hand once, it looks so strange but it was working fine for him. He had lost his thumb in a work accident, a machine just cut it off and crushed it.
I broke my wrist 2 months ago. Severely. It broke a piece off of the radius bone and the surgeon pinned that back together and inserted a dorsal plate for three months. It ties the index finger bone to the radius bone to help lock my wrist in place while it heals. Take care of your hands. It sucks using only one hand for things. Great video explaining the hands.
Precision is what makes our hands amazing. While most apes easily have greater strength in their hands, we have greater control and balance amongst other things.
We were informed early on about hands and in several the hands are covered. All these offer us to appreciate ourselves and how to help and understand. That info about the nail purpose makes perfect sense.
thats the reason why most of this channel previous video blur the finger part becos he already mention it may be repulsive to some viewer time over and over again, someone like you for example, but this video dont blur it becos its what the topic focus about
I have made arrangements with the University of Washington to donate my body for training and anatomical study. Having watched several of your videos, I feel that I have made the right choice. Thank you!
thank you so much for this video!! As a still young artist, I find knowing how structures work to be extremely important. I hadn't found an in-depth explanation of how the hand works that actually explained why those traits are necessary. Your video actually showed explained those parts, and I can't explain how cool this was to see!
i just wanted to say i really appreciate your warning in regards to the content of this video. as someone who started working with cadavers for my degree recently I really agree with what you said about the fingernails and finger tips. I thought going in that it might me other features that would bother me about the cadavers but I was super surprised when the thing that bothered me the most was those features on the cadavers over everything else (bar maybe facial features). I feel like people really underestimate the impact of such little things so I really do think its amazing that you did give a warning for that considering I feel like most people don't really take it into consideration after working with them for so long
It's very wishing moment to looking about what we are and made of so thank you to explaining so good way and I personally say people usually don't get interest in this topics due to bodies and cadavers but you and your team are spreading knowledge in good informative way so it's good to seen this videos in future I will like to donate my body to medical science which can be proud by self and once again thank you 👏👏👏
I had a partial degloving accident of my left wrist at the base of the thumb that tore the skin an inch long, and reflected a one inch section of skin back from over the carpel tunnel. It exposed the nerves and tendons over about an inch square. I'm not squeamish, so the doctor had some fun giving me an anatomy lesson while watching the tendons moving as I articulated my hand. I think we were both fascinated. Then he sewed it up.
Really? No wonder all dead humans I've seen have been fictional or dressed up in a funeral. We need to get a more realistic perspective on death. It's been cleaned up so much that it's easily ignored and not properly planned for.
This made me wonder about the process of aging. I was a teacher for 30 years and, by necessity, handled thousand of pieces of paper. The last few years before retirement I found that shuffling paper, that is separating one piece from another, was becoming increasingly difficult. I hadn’t noticed any reduction in manual dexterity. My question is, was this increasing inability due to wearing off of the finger ridges, lack of sweat being produced and being exuded along the ridge, or age related lack of oil production? I figured that it was a sign that I hang up my red pen and head for garden🥴
My hands are so dry that I can't open a bag, leaf through pages, or even leave a fingerprint without getting them a little wet first. By the way, prints harder to identify after a crime than most might think even if you have well-defined ridges. Hey, that gives me an idea...
I've found that my increasingly dry hands make paper handling very difficult. I have to lotion them and remove any excess product prior to any extensive paperwork chores.
This video is really so well made! and thank you to the people that gave up their bodies for the growth of knowledge and science! and thank you to you for making this wonderful video.

I am an artist, so I am fascinated by the human hand because it's one of the most difficult parts of human anatomy to draw accurately. It has such a huge variation in positions that it's very easy to draw these positions wrong. Studying hands is essential for all artists. Thank you for sharing all this info!
I'm here as an artist aswell. Looking to understand the machinations of the hand to create a moving skeletal hand sculpture.
If you're looking to get to grips (pun intended) with understanding how to draw anatomy I can't recommend the Burne Hogarth Dynamic anatomy series enough. Or any book by them tbh. They have ones on hands, faces, the body, dynamic lighting and shadows and wrinkles and drapery. I think they're quintessential for anyone looking to draw the human body
When you made that disclaimer that fingers and hands upset some people, I didn't think much of it. But when I actually saw the hand it sent chills down my spine. It truly is different than other cadaver demonstrations because it is so personal and relatable and seeing it disconnected from the body and moved around is very uncanny.
Its hard for me to look at... Its just quite scary
Its soo cool!
Imagine these guys using those hands for another purposes... Disturbing.
@@alejandroperez5368 dude…. What’s wrong with you.
Idk for me it invokes interest
Several years ago a concrete block fell on the tip of my left ring finger and smashed it almost completely off. I was wearing artificial nails at the time which may have saved the finger. At the hospital the doctor said it was like a tube of toothpaste. He called it a burst fracture and the the bone was essentially powdered. It wasn't until the following day that I realized the finger next to it was also broken. There was a chance that the finger would have to be amputated (also a chance that the finger would continue to fracture down). It didn't. He said eventually the bone fragments would find their way back together and form a lump of bone and knit back together; not the way they were but in some form. I guess it was true. My finger is malformed but unless you look at it you don't notice there is anything wrong. The nail has grown back completely normally. You do see a strange looking bone on the x-ray.
Those types of injuries are no joke. Glad it healed relatively well!
I am so happy you are still here. That stuff is scary.
My right hand ring finger nail was cut from the middle. The previous day actually my finger got snapped by the car door. It did hurt alot but nothing was visible maybe because it was nighttime and to this day my nail grows in the same way, cut from the middle.
@Samurai Nuts It does still hurt sometimes. It hurts if I smack it on something but other than that it's totally fine.
@@theanatomylab why is my one thumb has a black line?
Never thought about fingernails providing resistance for better grip force, but it's so obvious and simple when pointed out. Absolutely incredible.
I'm not so sure about that statement. Your skin rests against the finger bone and the nail is on the other side of that bone. No pressure is applied to the nail when you are gripping something. Unless you are gripping with just the fingertips, which isn't the usual way to pick something up.
@@chachacamel actually, he's very much correct. Just do your own demonstration. Close your eyes if you need to. Slowly grip some thing with your fingers, although you will notice the sensation of touch initially with inner part of your finger. Concentrate a little further and you can feel the pressure build at the outside of the finger or at the underside of the finger nail.
How it seems to work is this (although you are correct about the bone providing resistance) : as you squeeze something the fatty tissue on the underside of the finger is displaced outward and upward, some of it directly to the bone, but the rest of it is displaced around the bone. With the fingernail on the opposite side the skin and fatty tissue meet further resistance creating more pressure and improving contact area at the underside of the tip, hence improving grip.
You are also correct that this function is maximized when using just the tip. That in it self proves much of the theory. And that function, using the very tips of our fingers is a very special trait that we have.
Fingernails could also be there to protect the tips of the fingers.
@@chachacamel Your flesh, like everything else, will take the path of least resistance. When your fingertips apply pressure, the least resistance would be to go to the other side of the bone. The fingernails are little barriers to impede that movement, providing resistance for the flesh when it tries to move. This allows better grips and keeps more flesh there to cushion the bone. Play around with poking different parts of the fingers, you'll observe this behavior.
this video was made just for me. I've had a serious hand/wrist/arm injury, degloved, picture removing a latex glove.
The fact that the arm in the video was actually a person who lived , prolly helped his/her kids take his/her first steps ! Thankful to people who actually donate themselves to medicine !
Orr rather say for a video...
@@leox8279 probably used for study before and after the video. Also, the video itself is education, therefor is technically a scientific study for anyone watching. The body was still donated to science/medicine.
I guess most get there w/o ever asking
@@leox8279 this helps us learn…it’s not just a video
Just remember that those bodies that were "donated to science" may not always be a choice. Sometimes, patients die but their family could not afford to pay the bills to give the person a proper funeral, hence, they're forced to donate them.
I didn't expect it even after the disclaimer, but I gasped a little when I saw those fingertips. But then I just felt amazed and thankful to the person who, in a sense, lives on as a vehicle to teach others what we have to be so grateful for. Thanks for this excellent video, you are an incredible teacher and this is a really valuable thing you do here on RUclips!!🙌

@@moraleschrist2501 so random
Ohhh I see why finger tips and nails can freak people out now - they look completely different to the other preserved tissue so you've got very alive-human looking finger tips on a comparatively odd looking rest of the arm... almost like an arm that's got in quite a severe accident 😬
It’s a real hand
Skin vs. no skin, basically.
@@ulta1240 Yeah I know 😂. The sentence should've read like "alive-human looking" rather than "alive, human-looking" 😅
It looks as if someone's hand got degloved, but their fingertips remained
It's cuz they skinned the body except for the fingertips, probably to preserve the nails
This isn’t my passion but it’s still really interesting seeing how the human body is made and functions.

I’ve learned so much from this channel and have been binge watching your episodes. I had a thorn in my elbow for about 14 years and wondered my I never got any major nerve or muscle damage and these videos just gives me insight on how the body works.
This video teaches me more than my anatomy class in school
Remember guys, that hand and arm once had a name and personality. He's not scary but beautiful. Let us thank him for giving us a helping hand. 😊
I have to HAND it to You, that was a pretty good pun . All joking aside , You are right in saying that the cadaver arm /hand is beautiful and not scary . Seeing such astounding beauty and complexity surely makes me take nothing about how my Body is constructed for granted . I was not "grossed out " or "scared" . Being deeply spiritual , I was in awe when seeing this Video. Nature is AMAZING and the Creator is ENDLESS in Power, Majesty and Glory .

Watching this with extreme interest 4 hours after surgery on my hand and wrist after a motorcycle accident. Thank you for helping me understand the mechanism of my injury more in depth after watching this video!
How u doing 3 months later?
Absolutely love how you break it all down so quick and easy.
One day I was pruning a large branch, with large pruners. I put a lot of force on them with my hand. The next day, I could not move my right finger and it took a year to completely heal. Seeing this video, I was able to see that there are two ligaments, (at least) connecting to that finger: one flatter looking one along the top and one UNDERNEATH, inside the palm. That explains SO MUCH and now I see how the handle of the pruning shears, pressing in the palm of my hand, could easily damage that delicate ligament, with enough pressure on it. THANK YOU for this very descriptive video!! I learned SO MUCH!!
yeah tendon injuries are no joke!
The videos that get me are the ones you guys discuss the donors and their families. I tear up just thinking about it. Such a noble thing to do.
I love the way you can see the GENUINE excitement on this fellas face as he speaks. How awesome he ended up with a career which was so fufilling to his interests and skills
Thank you for teaching us brother!
Truly fascinating. As a professional pianist with well over 20,000 hours of playing behind me. This is amazing to watch and the number of muscles behind the work we do as musicians is just staggering. To think that all these do everything I need them to do at the piano is almost all done automatically is mind blowing. Thanks for sharing.
I'm in the same situation (15,000 hours*), and this stuff makes me consider studying for Physical Therapy to be a musician's doctor....
@@smeetsnoud1 yes it’s just incredible isn’t it ? I love learning about this sort of stuff.
We are wonderfully and fearfully made! The complexity shows a clear designer who put us together! I have A huge W scar on my left wrist and hand from surgery after my wrist was broken in a fall. The surgeon must have been really skilled to navigate and repair that area!
It’s shows your ignorance to biology and how nature operates. There’s no evidence we were created nor had a creator.
What is also really amazing is the touch sensitivity of the fingertips. They can measure exactly how much pressure the hand and fingers should apply for a good grip. My dear Wife lost that sensitivity in two fingers and she keeps dropping stuff just because she cannot feel the grip!
really? thats pretty cool, ngl
i knew abt the sensitivity as theres many touch receptors in the fingertips, but i didn't know abt the measuring pressure of held objects
Finally, my morbid curiosity has been satiated 😂
Ever since you mentioned that cadavers' fingertips gross people off, I've been curious to see what they really look like
Same! I actually found a few vids where the hands weren't covered up and just thought people are weird. It doesn't phase me at all. I enjoy this type of content and I'm not easily grossed out. But yeah the uterus they found on the old lady cadaver had her hands exposed
@@tanyavandermerwe8330 Oh, I didn't notice that! I'll have to go back and watch that video again
Grateful to #Doctorojie who finally cured my herpes
I think it's that the skin is still on and so it's so much more visually obvious that this is a real person's hand, so it freaks people out.
omg same
I remember not being overly sensitive to the cadavers in the lab until I saw one lady with hands/fingers like my mom's that still had fingernail polish on. It's amazing how polish survived all the embalming fluids.
My mom had passed away the same year which is why it bothered me.
You mom is proud of you!
Damn that must of been weird a lady's hand that is just like your mom's hand probably was also creepy at first
3:40 I broke my thumb after a motorcycle accident recently and had to have it in a cast for a month, even though I had completely free movement of the remaining 4 fingers I couldn't believe how many simple tasks I couldn't perform without struggling or help from my other hand, thumbs are underrated!
Let’s all give him a big hand for his efforts
👏👏👏👏👏 and you for this pointed comment
NAWWWW
When I saw those fingertips, I couldn't help but wonder at the fact that they belonged to a person who had to have atleast lived to their twentys and probably further. I kept wondering if those fingertips once carressed a child's cheek, once held a lover's hand tight, once gripped the bar of a rollercoaster, and so on. These kinds of videos really put being a living creature made of meat in to perspective.
In another video they explained where they got their cadavers and what information they get provided. They know very little: only the name, age and cause of death, if I remember correctly. The cadavers were definetely 60+ and mostly around 70 or 80 years old. One cadaver, maybe this one even, was from a lady who died of natural causes around 90+ years old :)

The human body really is just amazing. My mom had an accident last year, she fell into our empty pool while we were emptying it to clean it, and broke both of her wrists, her right shoulder, and her left foot. She had surgery twice on the right wrist but the left one was relatively okay, though both still give her pain and slight difficulty moving. She can't make a complete fist and her thumbs aren't as flexible as they were before. She also has some numbness in her right arm, starting from her mid-forearm and going down her pinky and ring finger, so we think one of her nerves was damaged too. Obviously this has been really difficult and tragic, and I've done my best to take care of her and keep her pain at a minimum/advocate for her medically. But I also can't help but think that the hands and wrists are just so cool and our bodies are so resilient. (And, of course, I'm really grateful my mom survived the fall and her injuries weren't as severe as her neck or spine breaking!)
it's truly scary to think about how our lives might change in the blink of an eye
I got a distal radius fracture in my right wrist, and also fractured my scaphoid and damaged some of my wrist tendons in a snowboarding accident last winter. Recovered now but after watching this its clear to see why my entire hand and upper forearm was also affected as a result. Crazy how many muscles and different tendons work together to move your hand and wrist. These videos are very informative and fun to watch, thanks for teaching all of us!
Half the time (mostly during tendons & ligaments part) I was reimagining/remembering muscle vein & bone anatomy posters/images I've seen so many times. Those few main nerves, like with veins, going to the hand (like in feet) then branching out in so many... like small channels (rivers) or small then tiny roots.
Thank you professor, it's a major task for artists to depict hands, and it's incredible how the human body works!! Everyone at this channel is so good at teaching, that I always get fascinated at the videos!! Thank you for sharing your knowledge with everyone!!! ❤
I had a disk on a high speed grinder explode and it destroyed a good part of my left hand. Through many surgeries over a few years I have regained reasonable use of the hand again. One aspect that amazes me is how parts of our body sort of regenerates. I was missing a silver dollar sized chunk of flesh in the palm just under my little finger and ring finger. Although the surgeons transplanted veins to replace arteries, tendons and nerves, they opted to just leave that chunk of skin and flesh open to heal on its own. Although it took nearly a year, not only did the skin grow back over that area but the same palmer creases appeared as well as the same ‘fingerprints’ formed anew in the missing area. I just found it interesting that missing chunk grew back. Now if I could just get that dang little finger to move when I want it to and not decide to move when I don’t expect it to move!
As someone who is planning to become a physician, I'm in love with your videos and thankful for them 💗💗
That’s so weird to see the hand of the dead person but also interesting
its just meat
That shit is creepy
Need a hand?
I totally agree with you-the only time it bothered me in the anatomy lab was when I saw an older woman with her fingernails painted. I started thinking about her life and that someone cared enough to paint her nails. I had to walk out and cry a little before I could return and I hardly ever cry.
I fell over last week and sprained my thumb, it’s fascinating to see the structures of the hand while gently probing the parts that are tender and seeing the affected areas :)
Seeing you handle those big nerves in the forearm made me think of Aron Ralston who had to amputate his own arm to free himself. He said cutting through those nerves felt like sticking his arm in hot magma.
I've heard of him. It's crazy how he was able to do it 😬
I remember him saying something about how the nerves looked like spaghetti and they definitely do
Liquid hot mag-ma.

It's truly amazing how complex our hands are, especially when playing musical instruments with them. Though it would be neat to see you guys cover the insane complexity of the human feet. I'm sure many barefooters (and organists) would love to see your take on them, especially with the barefoot movement growing a lot over the years.
I think playing musical instruments speaks more of our abilities of memory and the brain rather than the hand. Unless you are playing your instrument very fast.
@@manumusicmist what makes you think that?
@@dominikweber4305 because most musicians play with muscle memory and only need to learn how to play at the first time. And that learning mostly is about forming memories of the right way to play. :)
@@manumusicmist i know, i play the guitar. I think the original commenter was speaking of the actual physical complexity that is needed to move your hands in such nuanced ways

Very interesting. I’m recovering from having broken my left wrist and forearm into 15 pieces. It has 3 pins and a cast and at this time it is no help to the right hand. It’s amazing how much one useful hand feels lost without the other other.

I remember when my girlfriend was studying anatomy in med school. When she was working on the cadavers arms she could not eat chicken legs for a year or so. Me being a lover of dark meat and going to school to be an electronics engineer happily took the legs.
Hahahaha that’s funny!
I was thinking how much it looked like chicken meat.
I had the same feeling watching this video! That human arm/hand looks like a chicken leg, and we eat chicken legs.. so almost like someone would eat human arm/hand? Brrr I know its abstraction but gave me chills. No chicken legs for me too for a while!
I was mentally berating myself that it was a sick thought for me to think it looked like chicken. Glad to know I am not alone in this thought
That’s going to be me after seeing this😩
I'm eating chicken legs while watching this video 😎
Would love to see a follow up video of the pulleys, and boney structures that work to make the actual motions of the hand, pivoting surfaces and joint capsules! Awesome video! Studied the hand specifically for over six months for a project in mechanical engineering! Its a fascinating topic!!

As a robotics designer wannabe, attempting to approximate the complexity of the human hand is DAUNTING, to say the least. I appreciate and love all the work that Nature put into developing the hand (muscles, tendons, bones, ligaments, nerves) and the brain (to control this "output" device as well as interpret sensory data, i.e. "input").
"Simply" fascinating. THANKS, so much!

I cut my hand almost completely off about two years ago, made me realize how complex the hand is when the surgeon explained putting it all back together. Only thing I didn’t cut through was my palm skin an pinky finger area
Great job. You guys do a great service educating everyone on the human body.
Never ever tought about any of this... Guitar playing just got way deeper
For sure!! lol
@Ziplokk yes indeed...piano..guitar..holing a microphone..pressing the buttons in on a saxaphone...holding drum sticks... hands are pretty clever parts of the body x
@Ziplokk Yes you are quite right, i dont play sax but can only imagine to what extent the hand and fingers are required for that...I play guitar and keyboard but my main use for my hands musicaly is a microphone, so my hand muscles are not needed as much as yours are he he , i hope you have a great weekend and i enjoyed reading your comment this morning, nice start to my day, take care x
@Nombre Apellido I'm thinking of Tony Lommi of Black Sabbath. While working at a metal sheet factory, Tony lost the tips of his right-hand middle and ring fingers, which made fretting the guitar impossible. He first tried playing the guitar with his right hand - but when that didn’t work, he first molded plastic tips to protect his fingers and re-adapted his technique. Then, as bending strings was tough on him, he also tuned down his guitar, going from E to C# - and so, the down-tuned, heavy metal guitar sound was born. Pretty amazing.
Like the hand, eye is also said to be an extremely complex organ. Can you please make a video on that one too, if its possible? It would be really fascinating to see how the eye, beyond our common knowledge, works.
It’s interesting how similar the overall structure is to other animals. The front shanks of a deer, for example, are the equivalent of our forearms.

Some weeks ago, I had flexor tendon repair surgery with some complications. This video made me understand my surgeon's thought process while repairing my pinky tendon. He explained but looking at a real hand I now get why he proceeded the way he did. Everything regarding hands is too complex to take lightly, but simultaneously it is truly mesmerizing.
As a OT with the specialization on hand, this was fascinating to watch. Took me right back to our anatomy classes where we had to prepare cadavers and differentiate between the different ligaments, nerves, muscles and how many things can go wrong. We mainly had the focus on different illnesses, deformities and diseases, and how they affect the hand. We rarely had a physiological opportunity to see and prepare. Did you by chance already made a video about m.dupuytren? I still try to find a way to make it more understandable for clients.
I was in the high school library one day and saw a book titled "Hands" or "The Human Hand" or something like that, not sure what exactly... I read a few pages, mostly looked at the pictures, just showing diagrams of the human hand, the bones, all the muscles, tendons, etc. and it has fascinated me ever since then. Sometimes when in boredom I just look at my own hand and wiggle my fingers just to see all the things moving around. I have such skinny hands that I can even see the veins moving around as I move my fingers. It really freaked out my classmates when I did this lol
we all can see that,it has nothing to do with having skinny hands
You sound like you have very beautiful hands I find thin hands beautiful more so if they are delicate!!
This was amazing! A little weirded out by the hand, but not as bad as I thought! Would love to go more in depth on the hand and all of the structures and how they interact with eachother! Keep it up guys!!
about what he says on fingerprints: I have noticed this as well. I do a lot of rock climbing, and sometimes my fingerprints get pretty well worn off. I can still grip the rock just fine, but it makes it hard to fell different texture nuances without them. and touch id never works haha!
The mechanics of a finger nail make so much sense, I have busted my nail bed from jamming it between a 80 pound dumbbell on the bottom rack as the nail was falling off it would partially open like a trap door when I grab things 💀
Fun fact: the thumb is so important that for the people who lose it, the doctors amputate one of the big toes and make it become the new thumb. Saw it on a man's hand once, it looks so strange but it was working fine for him. He had lost his thumb in a work accident, a machine just cut it off and crushed it.

I broke my wrist 2 months ago. Severely. It broke a piece off of the radius bone and the surgeon pinned that back together and inserted a dorsal plate for three months.

Precision is what makes our hands amazing.

Rather than the mechanics of the hands themselves, I suspect it's the ability of our brains to control the mechanics of the hands.

i just wanted to say i really appreciate your warning in regards to the content of this video. as someone who started working with cadavers for my degree recently I really agree with what you said about the fingernails and finger tips. I thought going in that it might me other features that would bother me about the cadavers but I was super surprised when the thing that bothered me the most was those features on the cadavers over everything else (bar maybe facial features). I feel like people really underestimate the impact of such little things so I really do think its amazing that you did give a warning for that considering I feel like most people don't really take it into consideration after working with them for so long
It's very wishing moment to looking about what we are and made of so thank you to explaining so good way and I personally say people usually don't get interest in this topics due to bodies and cadavers but you and your team are spreading knowledge in good informative way so it's good to seen this videos in future I will like to donate my body to medical science which can be proud by self and once again thank you 👏👏👏

This made me wonder about the process of aging. I was a teacher for 30 years and, by necessity, handled thousand of pieces of paper. The last few years before retirement I found that shuffling paper, that is separating one piece from another, was becoming increasingly difficult. I hadn’t noticed any reduction in manual dexterity. My question is, was this increasing inability due to wearing off of the finger ridges, lack of sweat being produced and being exuded along the ridge, or age related lack of oil production? I figured that it was a sign that I hang up my red pen and head for garden🥴
My hands are so dry that I can't open a bag, leaf through pages, or even leave a fingerprint without getting them a little wet first. By the way, prints harder to identify after a crime than most might think even if you have well-defined ridges. Hey, that gives me an idea...
I've found that my increasingly dry hands make paper handling very difficult. I have to lotion them and remove any excess product prior to any extensive paperwork chores.
Thanks people. Seeing real anatomy and hearing those explanations, helps me with drawing and understanding hands well.
