I recently got a job at a hospital as an intraoperative neurodiagnostic technician and I'm here refreshing my knowledge of Anatomy. I watched this series when I was deployed and finally got the chance to use it in the real world. Thank you, Crash Course.
@@lindaw5695 Depends how old your dad is and where he is from. It's not that there are loads of doctors and nurses here. But essentially since after WWII it became too expensive and time consuming(at least 6 years before specialization) to train your own medical staff in the West. So Britian eg used its former colonies building the post war national health service on Indian doctors. You'll find most Western countries do similar things though that leads to a reaction often from former immigrants trying to limit immigration because who wants foreigners in their country. To relate this to the integumentary system immigration rules build the wall suspend green cards etc are like the skin barrier. Commercial product wipes out the indigenous homeostasis (pongy oils instead of becoming health care workers you train to be bankers and lawyers becuase there's more money in it for you) and then you need more product (selective immigration) to do the job of protecting your skin. Bit of a stretch but yeah there wold be a lot more doctors in India if they all came back home.
+maysee traysee Here we have most likely a 15~ year old edge-meister who thinks being adult or smart means being objective and seeing things in black and white.
my teacher makes us take notes of this videos every new unit and makes comments on where she wants us to write down some extra or where to leave out. so ya, crash course is pretty damn amazing.
Hank, in these past few years you have matured into one of the greatest communicator's and educator's on You-tube. I watch out of interest and thirst for knowledge not for help with an education program as many do, so I can only image how highly valued these video's are with those who are. Though this great resource was not available for my children's generation , I find it comforting to know that you will be here for my Grandchildren Damon and Jasmine when they need you. Thank you and every one involved.
Just to let you know, I'm watching this nervous system series to brush up on my basics as I'm writing a lit review for publication about chemotherapy-induced peripheral neuropathy XD Just wanted to let you know while these videos are awesome for those in AP bio/high school/college, us professionals also very very much appreciate the fun animation and clear-cut explanations as a way to brush up on our basics before having to talk in depth about glial cells and astrocytes and such.

First the nail through the foot, now a damn spider on my bare skin. Seriously Hank, it's like you're trying your hardest to make these examples as potent as possible.
These videos are a perfect example of how learning things does not have to be boring. It's all in the way they are presented. I remember going over stuff like this in HS/college and it was all just facts. You make it all come to life ❤️
I know! If only they were that adorable in real life. Actually, wait, no...that would mean each cell has a face, which means each cell is infinitely more complex than a single cell ought to be, which means AGH THE COMPLEXITY.
I'm so blessed to have such a good anatomy teacher at school, but these videos really help me put it all together visually in my head. Thank you so much for helping us struggling students out :')
I wish my professor explained the topic in this manner. Very effective breakdown. Thanks for the effort always. Hands down the best channel for bio lessons!
Humans make me happy :) especially when they just wanna help each other being awesome. *clears throat* Yo Crashcorse the allmighty knowledge bringer!! Can you tell me what the artist's name is that has created what it is that music's at the end of your shows? I Really really really really like Really want to know, its such a light, productive, happy sound and yeap :p
seriously......what have been trying to understand for the past few days.......u explained it in a way i think i can never forget in my whole life.....THANK YOU.......
This guy is hilarious! I feel so lost in my A&P class, then I watch these videos and all the sudden it makes sense! I actually enjoying learning about this when he is talking---My Proff. should take some notes
Watching these as I finish up my prerequisites for med school! The history and literature videos helped me so much in high school, and these are helping me in the "real world" too!
This is the best youtube channel ever Whenever I want to learn extra about something I go to Crash Course Please keep making videos for other subjects too!!!!!!!!!!!!
Thanks so much to C.C. as my A&P teacher is beyond dull and almost useless as a college-level instructor. This guy is funny and "animated" and seems to "live" this material. His humor and clarity have helped me because I've had to, mostly, teach myself the A&P I'm doing this semester. A good teacher is a unique type of person, and I'd say this guy's got that "special something". Thank you from a struggling student. Warm Regards.
I’m watching this to get to know my body better. I have fibromyalgia (overactive nerves). It helps to know how the system is supposed to work. Thank you for explaining in a way i can understand! Keep up the good work! 😊
This was by far the most helpful and amazing sort course! I study psychology and this channel has helped a lot through exams and tests. Thank you so much and keep up the awesome work!
Just again, wow. You guys at crash course are awesome. Using this in my science class for an overview of the human organ systems and it's much appreciated.
Thank you so much for making these videos! I am trying to get through nursing school. I am currently taking A&P and it is a lot of information to take in. Your videos help a lot. I'm more of a visual learner and all of your cartoon images help me understand a little more. Our lectures should consist of your videos. Lol. You're awesome! Keep doing what you're doing!
This is a beautifully made video (graphics, script, and oral presentation) and covers an enormous amount of information in only 10 minutes. Excellent work!
I'm a Japanese studying to become a pharmaceutical translator. This video helps a whole lot! It's really amazing every time seeing this man speak so fast so perfectly.
thanks for making funny science videos it rlly helps me study and take notes.its better watching this than it is reading some boring thing my teacher gave me... so again this was very helpful thanks :)
MAN YOU DO A GREAT WORK SPREADING INFORMATION AND EDUCATION FOR FREE TO STUDENTS AND THOSE WHO ARE INTERESTED FOR FREE . YOU SHOULD BE no 1 SUBCRIBED CHANNEL .
I did 4 pages of notes from this one 10 minute video, i learned more from this one video than i would in a 3 days of regular science class. Thanks Hank Green this helped me with notes I had to take for a science project
I'm studying to be a masseuse and learning all about the anatomy. The module information I have is lots of written work and a little overwhelming! Your videos are a huge help to me. You break down the key facts into more bite size info! Thank you! :D :D I can now actually process this!
I love the way you guys sum up everything in these short videos and still cover most important things. I am just learning from your videos and also noting down on my notes. Can you guys post the script in text-form so that we can follow the same topics for writing. thanks in advance
This channel has elped me in so many ways, with exams projects or even just to be etrentained, but especially the courses "anatomy & physiology" and "history" this two channels are the best
Who else is watching this because their teacher just gives out handouts instead of answering questions, lecturing, and creating good PowerPoints in order to help us properly learn the course material? I have a sneaking suspicion it's more than just me.
Svakalegt Or toes, apparently once having a toe some how leave your body it is Really hard to get used to it with all sorts of balance issues or so I've heard.
At 7:37 the graphical representation for unipolar is kind of incorrect because the one you are showing is called a "pseudo unipolar neuron" commonly found in dorsal root ganglion which has a axon and a dendron appearing extension
That was actually a really good artistic representation of a jumping spider. They're harmless (not significantly venomous) and only bite if you make them. Better yet, a few species are super-curious and will actively explore you. Really fascinating stuff.
Three principle functions:
- SENSORY INPUT (nervous system senses the spider on your leg)
- INTEGRATION (your nervous system processes the input, and decides what should be done about it)
- MOTOR INPUT (your hand shakes off the spider, it's a response that occurs when your nervous system activates certain parts of your body)
NERVOUS SYSTEM DIVISION
--- CENTRAL nervous system - CNS
- brain
- spine cord
--- PERIPHERAL nervous system - PNS
- around your body
- SENSORY DIVISION (afferent) - picks up a sensory stimuli
- MOTOR DIVISION (efferent) - sends directions from your brain to muscles and glands
- SOMATIC nervous system - voluntary (skeletal movement)
- AUTONOMIC nervous system - involuntary (heart, stomach, lungs)
- SYMPATHETIC - sends the body into action
- PARASYMPATHETIC - relaxes the body
- Neurons (small part of your nervous tissue)
- Glial cells (50% of mass of your brain)
- provide support, nutrition, insulation, and help with signal transmission in the nervous system
- GLIAL CELL TYPES
- CNS
- ASTROCYSTES - support, regulate ions, exchange materials between neurons and capillary
- MICROGLIAL CELLS - defense against invading microorganisms
- EPENDYMAL CELLS - create, secrete and circulate cerebrospinal fluid
- OLIGODENDROCYTES - wrap and insulate, form myelin sheath
- PNS
- SATELLITE CELLS - surround neuron cell bodies
- SCHWANN CELLS - insulate, help form myelin sheath
1. Neurons are some of the longest-lived cells in your body.
2. Neurons are irreplaceable. Most are AMITOCIT - when they get assigned a role, they can't divide anymore.
3. Neurons have huge appetites. They need a lot of oxygen and glucose. About 25% of daily calories are consumed by your brain
NEURON STRUCTURE:
- Soma - cell body
- Dendrites- listeners
- Axons- talkers
NEURON TYPES:
MULTIPOLAR neurons
- three or more processes
- one axon, bunch of dendrites
BIPOLAR neurons
- one axon, one dendrite (found in special places - retina of your eye)
UNIPOLAR neurons
- have only one process (found in your sensory receptors)
NEURON FUNCTIONS:
SENSORY neurons - afferent neurons
-> transmit inpulses from sensory receptors toward the CNS
-> mostly unipolar
MOTOR neurons - efferent neurons
-> impulse moves from the CNS to the rest of the body
-> mostly multipolar
INTERNEURONS - association neurons
-> impulse moves between sensory and motor neurons
-> mostly multipolar

I'm more of a visual learner and all of your cartoon images help me understand a little more. Our lectures should consist of your videos. Lol. You're awesome! Keep doing what you're doing!
This is a beautifully made video (graphics, script, and oral presentation) and covers an enormous amount of information in only 10 minutes. Excellent work!
I'm a Japanese studying to become a pharmaceutical translator. This video helps a whole lot!
It's really amazing every time seeing this man speak so fast so perfectly.
thanks for making funny science videos it rlly helps me study and take notes.its better watching this than it is reading some boring thing my teacher gave me... so again this was very helpful thanks :)
The only educational videos I don't have to put at 1.5x speed
You guys will keep making scientists! Just mind blowing! Hats off!
MAN YOU DO A GREAT WORK SPREADING INFORMATION AND EDUCATION FOR FREE TO STUDENTS AND THOSE WHO ARE INTERESTED FOR FREE . YOU SHOULD BE no 1 SUBCRIBED CHANNEL .
I did 4 pages of notes from this one 10 minute video, i learned more from this one video than i would in a 3 days of regular science class. Thanks Hank Green this helped me with notes I had to take for a science project
"THERE'S...NO THINGS- there's things..."
lol gets me every time

Benjamin Natividad I loved this too
when you have an existential crisis in the first minute of a video
Haha! So rel@table!!!>
Omg I am so happy to have found this channel!!! You guys are a gift lol I was panicking over my Anatomy exam
Loving this series so much, it's absolutely fascinating!
Love your videos. I usually watch it at 0.75 speed because it is new information to me, but it is helping me stay consistent with my learning.
I'm studying to be a masseuse and learning all about the anatomy. The module information I have is lots of written work and a little overwhelming! Your videos are a huge help to me. You break down the key facts into more bite size info! Thank you! :D :D I can now actually process this!

Nice...wait was that a Standard Deviants reference...if not that's basically what they said.
You can't overCELL the importance of the nervous system.
Okay, I'll go away
Freyjaa Singh Kirti lol i was about to see the cool reply, but then i saw ur reply lol
Freyjaa Singh Kirti haha appreciate it!
Yes, but actually no, because you are simultaneously gone and still here. How would we know?
Ik this is 2 years old BUT I THOUGHT THE SAME THING HAHAHAH
Almost 5 years later and this is still incredibly helpful - love crash course
Crash course coming to our rescue once again
This is the best site for learning A&P and understanding exactly how the different systems interrelate. This guy is so much fun to listen too!
I'm sorry but did anyone else laugh so hard when he said "there's things" 0:57
Tatenda Mahaka i didnt u derstand oh gid
Thank you soo much ! helped me a lot. This 10 minutes helped me than a 5hr lecture!!
0:38 I'll make sure I'll remember that for the test tomorrow

I love the way you guys sum up everything in these short videos and still cover most important things. I am just learning from your videos and also noting down on my notes. Can you guys post the script in text-form so that we can follow the same topics for writing. thanks in advance
This channel has elped me in so many ways, with exams projects or even just to be etrentained, but especially the courses "anatomy & physiology" and "history" this two channels are the best
Who else is watching this because their teacher just gives out handouts instead of answering questions, lecturing, and creating good PowerPoints in order to help us properly learn the course material?
I have a sneaking suspicion it's more than just me.
Learning is so much funner when everything has a stupidly cute grin. :D
Dear Crash Course,
Will you ever do a geometry series?
CrashCourse hasn't really ever done mathematics courses...but I suppose there's a first time for everything.
Or mathematics generally? I want the Crash Course spin on algebra.
Just stumbled over this channel - on first glance it seems AMAZING! This is why i love the Internet - Thank you!
i hope we can all be as happy as the astrocyte!
was here for my a&p tests, now im back years later as my hesi exam is tomorrow for nursing school
I feel like this video is highly biased. Of course the brain would say it's the most important organ. :P
It's very sneaky and self-important like that.

Yeah, screw the brain, what would you do without your sweet sweet fingers!?
Svakalegt Or toes, apparently once having a toe some how leave your body it is Really hard to get used to it with all sorts of balance issues or so I've heard.
But without the brain, none of these would do anything
Darshan Shah my brain was opened
At 7:37 the graphical representation for unipolar is kind of incorrect because the one you are showing is called a "pseudo unipolar neuron" commonly found in dorsal root ganglion which has a axon and a dendron appearing extension
"Hey hand part, how bout you do something bout the spider" LMAO
The best part hahahah
2:57
I watched your videos on philosophy back in 2017, and man you still have my heart!
This video is pure gold. You made my professor’s complex and hard description of the nervous system so easy to understand. thank you!
the spider looked so cutesy :D
Nothing to be afraid of here! Just your friendly, adorable, neighborhood Thought Café animated spider.

he needs to be a more regular feature, spiders are so misunderstood! Unlike wasps, wasps are super meanies :S
No. Just... no. Kinetic bombardment from orbit is the only solution.

Man, I hate wasp. #SourcefedNerdCrossreference
That was actually a really good artistic representation of a jumping spider.
They're harmless (not significantly venomous) and only bite if you make them. Better yet, a few species are super-curious and will actively explore you. Really fascinating stuff.
Omg!! Thank you . You make it so easy to study ❤️❤️❤️❤️
+1 to ThoughtCafe for the, umm... dangling... animation at the mention of "glands".
I wish I could work for you guys!! I love crash course. It helps me learn new things, and stay brushed up on the old. Thank you for all that you do!
