Everything about your videos is wonderful. You are an incredibly gifted instructor; not only is your editing and artwork intuitive and helpful, but also the way you organize the material and even your oration in presenting the material make a challenging course like anatomy accessible, especially to those that struggle like me. I am so thankful you have chosen to make your work freely available on RUclips. After studying hard and watching lots of your videos, I was able to swipe an A on my first lab practical and anatomy midterm. I owe a lot of that success to you! I will definitely be following you throughout my education and beyond for sure! With thanks, A first-year PA student.
please never stop making videos!! anatomy doesn't come naturally to me, but your videos make anatomy much less intimidating (and less serious)!! thank you so much! (from 2nd year UK medical student)
You don't just explain stuff crystall clear but also show the way to sum things up, you also teach to learn easy. Thank you so much. You have contribution to me and many others in being a doctor and help people, what you do is nobel.
As an art student, this is so incredibly helpful to understand the functioning of the body, you have a way to explain things that make everything easy to understand and remember. Thank you!!
Hi, David I just found out this your 'You Tube' channel....U taught my 'Optometry class as a visiting lecturer back in Ghana. Now in med school myself and I'm enjoying your video all again. Thanks🙏
Hello Kwabena, it is great to hear from guy again. Congratulations on finishing optometry school and continuing your studies in medical school. How are things going?
Your videos are so very helpful! Thank you for sharing them. A note on this one - you say the aconeus assists the trapezius for elbow extension - I think you mean triceps.
I would just like to add that the m. abductor pollicis longus originates on the posterior middle 1/3 of the radius, ulna and interosseous membrane m. extensor pollicis longus can originate on the posterior middle 1/3 of the ulna and the interosseous membrane m. brachioradialis inserts on the suprastyloid process of the radius m. supinator has 2 heads a superficial and deep, the posterior interosseous branch of the radial nerve goes in between them m. anconeus is actually really usefull! i heard if removed patients can loose up to 40% of extension strength in the elbow joint
Loved your explanation. Recently after a 14 hour mountain trek under a hot sun and forearms being sunburnt from holding on to a climb support rod, am not able to extend my fore, middle and ring fingers.
Dear Mr. David, Could I use your info. on Yoube as a reference by mentioning your name and the link,ect? I am writing something about tennis injury now. Your stuff is so great as a source of anatomy knowledge to the tennis fans.
Urgh, the pain of the complexity. But thanks for the video, it's a huge help. XD I'm actually learning how to draw instead of medicine or anything, and your videos are very useful when it comes to understanding anatomy, so thank you very much once again. ^_^
Once I'm done understanding this one and the other arm/elbow/forearm related videos - which might take a while considering all the different angles, perspective and stuff - I'm certain I'll be finally able to make peace with drawing arms and hands. XD
The "anatomical snuff box" is named for its historical use as a location for inhaling powdered tobacco, known as snuff, years ago (like 18th century-ish).
1:30 Isn't the "back" of the forearm the posterior side and contains the flexors while the "anterior side" is best described as the top of the forearm when held out parallel to the ground and contains the adductors? I'm completely lost now.
CrucifyRobinHood, back can’t be flexors, because the contraction of that set of muscles would open up/ extend the forearm/elbow. Don’t confuse arm n forearm.
A very important question for you. Which muscles (taken as a whole) have more potential for hypertrophy: the forearm extensor muscles (mentioned in this video) or the forearm flexor muscles? Thank you so much for your informative videos.
You know ... I don’t know the answer to that question. There are 2 major finger flexors and one major finger extensor but if one set can get bigger physiologically I don’t know. I surmise that I would see hypertrophy more in flexors than extensors.
Please correct me if I'm wrong. The Brachioradialis doesn't have any extension functions, it flexes the elbow and helps with supination but it' considered a forearm extensor because it is supplied by the radial nerve. But is it considered a posterior forearm muscle or anterior because it lies anteriorly?
You are correct. The brachioradialis flexes the elbow and is found in the posterior compartment of the forearm and thus innervated by the radial nerve.
It looks like it does but the brachioradialis is actually part of the posterior forearm osteofascial compartment. As such it is innervated by the radial nerve. It seems like the odd man out because it flexes the elbow where the remainder of the muscles in the posterior forearm are extensors.
Update: it did -I've got elbow pain from volleyball, false grip and just lots of pulling movements. It got so painful that it felt like my arm would tear off after spiking. Anyways temporary remedy was just deep tissue massaging and that massage gun. Helped short term, but pain was still present and much less painful would feel I could only describe as "sticky" in my forearms. I say it like this because I'm sure many people have gone thru this, and guys all I did for like 30 min was putting my fingers thru a hair tie and just open and close it. Add more for extra resistance, less for more ROM and isometrics. Felt a great burn in the extensors and could literally feel the exact spot of pain and pressure releasing. This has been bugging me for about 2 years now and it feels like I just found the cure for tennis elbow. I wish someone with this problem will see this and have success! Ps: apologies for the word splurge
@@TheNotedAnatomist Im not sure, maybe looking at it wrong or the thumb is the wrong side or maybe the position of my hand, Been trying to feel every muscle in my forearm as some sort of therapy from an injury, so when i do an exercise i can access my forearm and hand more accurate and deeply as a whole, im looking at it on position where im facing my knuckles ...
I'm so emotional at the moment I'm so glad that I found your channel, sir you're fantastic

Thanks Ellen... that is very kind of you. All the best in your studies.
BTW ... do u have any suggestions for videos to be created?
@@TheNotedAnatomist hmmm maybe something combining clinical anatomy of upper/lower limb, or nerve injuries? e.g. claw hand, foot drop, wrist drop etc

Really helpful , i watch before dissection classes and it makes it easier
Man deserves a Nobel prize
U made my life easier in anatomy ! Love from India 🇮🇳
This make my gross anatomy class so much easier to comprehend! Thank you.
you are amazing. i just connect with how you give information. talented teacher and anatomist
Dear Anatomist, You are a hero and your videos are a amazing

Hello Kwabena, it is great to hear from guy again. Congratulations on finishing optometry school and continuing your studies in medical school. How are things going?
Thank you sir! You are a live saver, i hope you get everything you wish in life
Loved it, i literally can explain each of the muscles of extensor compartment
Finally, I've been looking for so long to understand the different layers of forearm muscles, thanks a lot
Wonderful! thanks Laura. All the best in your studies.
Wow! Thanks so much for all your lessons. You're a great teacher.
Wrist flex ion stretch
Very well explained sir..... And specially the examples u give are spot on.... Can't thank u enough... You've made anatomy far more easy.
Oh, I repeated this lesson so much and can't understand the big picture. Thank you very much. I appreciate it.
Thank you so much! U saved me from a panic attack! Awesome explanation!
I love this guy !! he is my anatomy hero 😇
Wow! Finally found an adequate video! Thank you very much!
This makes me cry
god bless you..
YOU'RE A MAGICIAN. ✨
YOU MAKE EVERYTHING SOO EASY TO UNDERSTAND AND MEMORIZE. I HAVE EXAMS STARTING IN 2 WEEKS. GREAT HELP❤️❤️
Thank-you Alisha.
Outstanding video. Best explanation i could find
Thank you for making it easy to remember.
( 6.42 ,it’s Triceps not Trapezius , slip of tongue )
This was enormously helpful!! Thank You so much for this lecture!!!
You're very welcome!
Thank you so much! I have my muscle eval coming up in a few weeks and your videos have given me hope! Also helped me ace a bone eval😁
Glad I could help!
6:40 " the Anconeus muscle assists the Trapezius muscle in extending the elbow " you meant the triceps right?
+ahmadharb13 Doh! Thank-you ... you are correct.
All thanks to you and your videos
You are most welcome.
:)
This was INCREDIBLY helpful! Thank you
thank u so much for this
You're very welcome!
i loved the part of snuff box it really made my mood to study
all the very best for your upcoming activities
❤ love n respect from 🇮🇳INDIA
Hey, thanks for this video. At 6:40, do you mean assist the triceps in extending the elbow? Not the trapezius right?
Doh! Yes you are correct ... Thank-you for letting me know:)
Your videos have helped me so much. They are amazing. Thank you !
absolutely AMAZING lectures and workbooks!
ayee brah my man over here doin da gods work
Muscles of the Forearm - Posterior compartment
Superficial: (lateral -> medial)
1. Brachioradialis
2. Extensor carpi radialis longus
3. Extensor carpi radialis brevis
4. Extensor digitorum
5. Extensor digiti minimi
6. Extensor carpi ulnaris
7. Anconeus
Deep: (proximal -> distal)
1. Supinator
2. Abductor pollicis longus
3. Extensor pollicis longus
4. Extensor pollicis brevis
5. Extensor indicis
Your videos are so very helpful! Thank you for sharing them. A note on this one - you say the aconeus assists the trapezius for elbow extension - I think you mean triceps.
The roof of the anatomical snuff also has cephalic vein... BTW it is a wonderful video
You DREW these??? These are amazing :OOO
I would just like to add that the m. abductor pollicis longus originates on the posterior middle 1/3 of the radius, ulna and interosseous membrane
m. extensor pollicis longus can originate on the posterior middle 1/3 of the ulna and the interosseous membrane
m. brachioradialis inserts on the suprastyloid process of the radius
m. supinator has 2 heads a superficial and deep, the posterior interosseous branch of the radial nerve goes in between them
m. anconeus is actually really usefull! i heard if removed patients can loose up to 40% of extension strength in the elbow joint
fantastic video thanks. the human body is amazingly complex
6:40 For anconeus,, u mistakenly said trapezius instead of triceps
YOU ARE THE BEST!!!!
Thanks Dr. Great explanation no i understand 👍
Now that was really really helpful....thanks a lot !!!!
This videos ARE THE BEST
Thanks a lot for ur easygoing information 🥰😍
Excellent video!

How did it go?
Why is it called the "anatomical snuff box"?
The "anatomical snuff box" is named for its historical use as a location for inhaling powdered tobacco, known as snuff, years ago (like 18th century-ish).
Great video thank you
1:30 Isn't the "back" of the forearm the posterior side and contains the flexors while the "anterior side" is best described as the top of the forearm when held out parallel to the ground and contains the adductors? I'm completely lost now.
CrucifyRobinHood, back can’t be flexors, because the contraction of that set of muscles would open up/ extend the forearm/elbow. Don’t confuse arm n forearm.
For ABL did you mean it originates on the ulna and inserts onto the base of the first metacarpal? At 2:40
You make studying fun!!
Hi, what kind of nomenclatura/book do you use for your videos. Thanks a lot
Love you videos
great video man ty
So how far is the EDC supposed to pull?
Two errors? Help trapezius (triceps) extend the elbow; go distal (proximal, as the animation shows) to the extensor retinaculum.
“Anconeus assists the trapezius in extending the elbow” I’m sure you meant triceps but just wanna put it out there.
Thanks for your correction
God bless you❤
Hi thanks so much for your videos. What are the origin and insertion points for the other digit extensors?
This is too good
What are the best exercises for tight forearms please

Right back at you from Utah!
thank you sooo much its helped me a lot

Mark Nielsen's anatomy textbooks.
Very geart really thank you❤️

Ok that's great thanks Professor.
thanks doctor!
Thanks man!
No problem!
Mmm. Mmmmmmmmmmmmmmm. Mmmmmmmmmmmmmm mmmmmmmmmmmmmm mmmmmmmmmmmmmmmmmmmmmmmmmk
R.Rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr 4
Anconeus aids the triceps to extend .... not trapezius
You are correct I misspoke ... thanks for the feedback
Do you think training the extensors will decrease the tension in other muscles of the forearm?
Update: it did
-I've got elbow pain from volleyball, false grip and just lots of pulling movements. It got so painful that it felt like my arm would tear off after spiking. Anyways temporary remedy was just deep tissue massaging and that massage gun. Helped short term, but pain was still present and much less painful would feel I could only describe as "sticky" in my forearms.

i didnt get how the brachioradialis extend the forearm
Thanck you
Thanks
Thanks a lot
Most welcome
The trapezius doesn't extend the elbow...
Nice

thanks alot
4:58 is a left hand, not a right hand
The hand is confusig me, it looks wrong for some reason ..
Hi Carol, in what way does it look wrong?
@@TheNotedAnatomist Im not sure, maybe looking at it wrong or the thumb is the wrong side or maybe the position of my hand,
Been trying to feel every muscle in my forearm as some sort of therapy from an injury, so when i do an exercise i can access my forearm and hand more accurate and deeply as a whole, im looking at it on position where im facing my knuckles ...
My ignorance is showing. Nevermind, got it now.

And we got extra tendons just to do rock on huh....
