Muscles of the Leg - Part 1 - Posterior Compartment - Anatomy Tutorial 

3 superficial muscles: -gastrocnemius: medial+lateral head on their respective condyles's facets, calcaneus via achille's tendon -plantaris: lower supercondylar ridge via medial tendon that joints calcaneal tendon -soleus: top tibia via calcaneal tendon 4 deep muscles: -popliteus: lateral femoral condyle to posterior proximal tibia, through joint capsule -flexor hallucis longus; posterior lower fibula to base of distal phalanx of toe -flexor digitorum longus; posterior surface of medial tibia to base of lateral 4 phalanges -tibialis posterior; interosseus membrane to tuberosity of navicular and cuneiform

Hello, thank you! Sorry for the lack of videos lately - have been away from home and extremely busy. Just invested in a new laptop so should be able to produce a couple of tutorials here and there, but will be back in full swing by mid-July. I have just got a few more musculoskeletal tutorials to do (as those seem to be in highest demand!) but I fully intend to get some up on the abdominal and thoracic viscera as soon as I can! So much to cover, not enough time! :)

Origin and insertion of popliteus muscle has been swapped around. So origin is the lateral aspect of the lateral condyle and the insertion is the posterior surface of the proximal tibia. Otherwise, amazing video, thank you so much!

i always watch these videos before an OSCE practical exam. thank you!!

Your tutorials are amazing & have helped me no end in learning anatomy. Thank you so much!

Studying Anatomy is incomplete without your tutorials. A BIG THANKS!!!

This is a brilliant tutorial for the beginners as each and every muscle is shown clearly and help us as a disector.It will be very helpful if you give the the courses of arteries ,veins and nerves distribution in your 3D tutorials.Keep it up.

4:28 is where muscles start. Good explanation.

Life saver channel of medical students

This tutorial is helpful, though I must admit, I personally would have found it even better if the muscles functions were demonstrated. Although I understood what you meant about moving the foot, I am the type of learner that would need a demonstration to rationalize it and thus be able to learn it. However, I do understand and respect the possibility that you may not be able to do anything but hide and show the muscles on a static figure for the sake of learning for medical purposes. Even so, I still wanted to share my opinion, just in case the option is available in future tutorials. Thank you!

man,,, you're just amazing THANK YOUUU !!!

Thank you so much! Studying to be a Personal Trainer and this is incredibly helpful!!!

Hey. Isn't the origin and insertion of popliteus the other way round? I mean, originates from the lateral condyle and inserted on the posterior surface of femur? Please clear this doubt. Btw, all your videos are very, very helpful. Thank you

You said INSERTION of Popliteus is on Lateral surface of later condyle of femur and ORIGIN is on the posterior surface of tibia. BUT I THINK IT'S THE OTHER WAY AROUND. Origin is proximal. Insertion is more distal.

Thank you so much! The way you operate the program you use to display all this is simply stunning

Actually, the Popliteus muscle originates in the form of a round tendon from the lateral surface of lateral condyle of femur and gives insertion on the Tibia above the soleal line. According to the law of contraction, the muscle contracts towards its origin , therefore, when Popliteus contracts, it pulls the Tibia towards the condyles of femur and in this way 'unlocks' the knee.

Such AMAZINGLY helpful videos you create! Can't thank you enough!!!

popliteus m. Origin and insertion is opposite, although your explanation is very helpful🙏🏼🤍

im learning this to help me exercise better knowing how the leg muscles work helps me not injure myself very interesting channel i like it very much so thank you .

wowwwwww!!!!!you represented it as best as possible!!!!THANK YOU SOOO MUCH..I LOVED IT!!

Excellent revision, wish it was there in our med school days!If only you could add muscle action through animation, plantar flex ion etc.

The insertion and origin of popliteus is opposite to what he says.. But other wise the tutorial is very good. Thanks

Thank you so much for the very clarifying video and explanations. I always wondered where the Fibolaris and Tibialis are located vs. each other.

these videos are amazing!! I wish I'd discovered them more than 3 days before my exams :s

You have the best anatomy videos i have seen, thank you very much.

THIS VIDEO WAS FANTASTIC!!!!

This is fantastic, thanks a million! I owe you a drink when/if I pass these exams!!

Thanks. This helps me massively!Great descriptions.

i can't thank you enough dude

Wow. This is the best ive seen….

Plantaris muscle takes origin from the 'lateral supra condylar ridge' of femur below the "lateral head" of gastrocnemius not the medial head. Its tendon swings lateral to medial in the calf and gives insertion on the medial aspect of calcaneus.

you made this difficult subjects so easy.thank you sooooooooo much.but this is a small request like nerve supply to a muscle please add blood supply of muscle too

Eversion is caused by the muscles of the lateral compartment, peroneus longus & brevis Inversion is caused by the synergic muscles tibialis anterior & posterior

Pronounciation note: in Latin, "c" followed by "e" or "i" is a "ts" or "s" sound. HalluTZis, or Hallusis longus. This actually is reflected in English pronounciation rules, too (think about when you pronounce a "k" sound for "c" and when you don't). Otherwise, very useful video!

Thank you so much for giving your time to do this. I am great full.

9:41 Isn't the origin of the popliteus muscle lateral condyle of femur and it inserts to proximal tibia?

U made it so easy

really help me a lot !!!

bloody great this, thank you!

Bro you recording on the set of birdbox?

i love your videos

amazing tutorial

Very informative and clear video!!! Thank you

This is a great tutorial. Thanks

Your videos are really useful. If u could keep videos from neuroanatomy,it would be grateful

yeah me too! the origin is lateral surface of lateral condyle of femur!

Gorgeous , don't know how to thank you 🙏🙏🙏

THANK YOOOU !!!!!!!!!!!!!! you're such a big help to me.. u can't imagine how much you've helped me :)

Great. A BIG THANKS MAN!!

there's a mistake in the popliteus muscle at 11:08 in our books I mean in snells cynical anatomy tenth edition the origin of popliteal muscle is lateral condyle of femur and its insertion is posterior surface of shaft of tibia above the soleal line even its like this on google too

الله يجزاك خير ❤

what software / programme are you using for this tutorial. It's very good

u told origin & insertion of popliteus muscle wrong!!

Really helpful video. In my book though the origin and insertion of Popliteus muscle was reversed 😅. Nevertheless great video. Please keep uploading

Is there an alarm going off in this video or is that just me?

Much gratitude.

great tutorial, thank you so much it is very easely understood,

Thank you

Thank you it helps me a lot toooooo. Thank u u make ma life easy

This is a great video. Thank you

Thank you a lot

thank you

Thank you so much..

Great video .....

This is fantastic, thank you so much!

You're too good

Awsome as always

The Plantaris muscle's action, despite its name, I think, is more useful for the inversion of the leg. Its origin on the lateral femural condyle and how it transverses the tibia medially would use it as an axis, so that when it contracts it would twist the leg inward.

Thanks!! Very helpful.

4:29 for muscles

it amazes me how all the sciences in its core are very simple and intuitive as soon as you translate them to normal language... the teachers always use this specilized words as if you suddenly suppose to know them all.. i always wonder if the teachers know them selfs what they realy mean.. from my experience so far they rarely do :( .. nice vid m8 pity the language makes it inaccessible to me.. time to learn some latin :)

so awesome ... keep it up Sir... this is very helpful

really helpful, nice job, thank you.

Greatly appreciated!

First, welcome back! :) Second, can you do some tutorials on the viscera like the gastrointestinal tract for instance? or the organs like heart, lungs, liver, kidney.. etc?

THANK YOU SO MUCH

Popliteus Muscle unlocks the knee at the joint via, Medial Rotation

really helpful

Didn't clear up a little bit, it totally made me a master of posterior compatment :) AND WHICH SOFTWARE ARE YOU USING? AND ITS PRICE?? THANKS AGAIN!!!

were there any children or people laughing!!?😂😂😂😂

you r great :) and also genius of anatomy !!! Thanks a lot

Amazing sir ❤️

thanks

thank u

Thank you very much!

very helpful.. Tysm

Thank yooou that's really great !

Thanku so much great

The anterior compartment causes "Eversion''. 1:48

Thank you for your help with anatomy:))))))

Some books say the opposite about the insertion and origin of the popliteal muscle. Which is true?

will u check the origin and insertion of popliteus? it is reversed in my book. do u know which is right? vg videos btw. love them!

This sounds just like a mate of mine (Y) the info is great

Can you please tell me which application or program are you using , it will be really helpful.

Tq so much sir

You're awesome!

Am I the only one who started flexing my toes when he talked about dorsal and planatar flexion?

it was awesome..

hi. great lectures thank you. I have been going through most of your videos. how can I learn the 3D or 4D video slide? this will help me with my teaching too.

What do you think of growing taller by sleeping with ankle weights? Letting your shins dangle off your bed while sleeping that way it pulls your cartilage apart and then the cartilage reforms and in return makes you taller.
