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! :)
please make correction regarding the insertion and origin of politics muscel
AnatomyZone thanks u back
First thing first: GREAT VIDEO!! -- A slightly 'critic' would go toward the Subtitle. Since the Video ITSELF is clean and for the MOST part white background. There is no need for you to give the FONTS (which is in this case: WHITE) a transparent BLACK background. That way the transparent BLACK-BACKGROUND is VERY destructive, VERY bulky and cover most of the time important massages. Keep it simple by changing the FONT to BLACK without any background, shadow or what have you! --- NO 'transparent black-background' is needed.
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!!
Exactly what I'm doing!!
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!!!
Thank you so much! Studying to be a Personal Trainer and this is incredibly helpful!!!
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.
Life saver channel of medical students
man,,, you're just amazing THANK YOUUU !!!
Thank you so much! The way you operate the program you use to display all this is simply stunning
wowwwwww!!!!!you represented it as best as possible!!!!THANK YOU SOOO MUCH..I LOVED IT!!
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 .
Such AMAZINGLY helpful videos you create! Can't thank you enough!!!
4:28 is where muscles start.
Good explanation.
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
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
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!
THIS VIDEO WAS FANTASTIC!!!!
You have the best anatomy videos i have seen, thank you very much.
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.
hi everyone ,if anyone else wants to learn about online courses anatomy and physiology try Pycanta Quick Anatomy Protocol (do a search on google ) ? Ive heard some decent things about it and my buddy got excellent success with it.
not if you're standing - the tibia isn't rotating towards the lateral condyle it's the other way around. Tibia is fixed in closed kinetic chain movement
Excellent revision, wish it was there in our med school days!If only you could add muscle action through animation, plantar flex ion etc.
Thanku sooo much ❤❤❤❤❤❤❤❤love from india
Wow. This is the best ive seen….
This is fantastic, thanks a million! I owe you a drink when/if I pass these exams!!
well did you?
popliteus m. Origin and insertion is opposite,
although your explanation is very helpful🙏🏼🤍
why is it wrong though? the origin is fixed and the insertion moves when a muscle contracts. when going from extension to flexion it's the lateral condyle of the femur that moves to unlock the knee (not the tibial insertion), which is why in this case the insertion is proximal

Thanks. This helps me massively!Great descriptions.
i can't thank you enough dude
Excelent presentation 👏
Awesome breakdown ✅✅✅
bloody great this, thank you!
الله يجزاك خير ❤
This is a great tutorial. Thanks
i love your videos
amazing tutorial
Gorgeous , don't know how to thank you 🙏🙏🙏
Great. A BIG THANKS MAN!!
THANK YOOOU !!!!!!!!!!!!!!
you're such a big help to me.. u can't imagine how much you've helped me :)
U made it so easy
Thank you so much for giving your time to do this. I am great full.
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.
Correct! Which means the Popliteus actually rotates medially not laterally
No it rotates the femur laterally ... But medially rotate the tibia in free leg
ahmed salah Just looking at a musculoskeletal book now, it says Action: Medially rotate the flexed knee (tibiofemoral joint) and Flex the knee (T/F joint) Originates: Lateral condyle of the femur Inserts: Proximal, posterior aspect of tibia. Nerve: L4,5, S1
Ok the origin & insertion are correct
But this is the muscle of unlocking
&unlocking means lateral rotation of femur in fixed leg &medial rotation of tibia in free leg
Never believe everything you read :P
Very informative and clear video!!!
Thank you
Thank you it helps me a lot toooooo. Thank u u make ma life easy
Much gratitude.
really help me a lot !!!
ana alvarado me also
Great video .....
This is a great video. Thank you
Amazing sir ❤️
Your videos are really useful. If u could keep videos from neuroanatomy,it would be grateful
The insertion and origin of popliteus is opposite to what he says.. But other wise the tutorial is very good. Thanks
No, I think he is correct coz my tutor also told me so.
Linnet Kipruto i checked on many websites and encyclopedy and it is the opposite to what he says
I have two textbooks that say it is the opposite as well so I came to comments to see if anyone else noticed or agree. I'm glad it wasn't just me.
Based on what I have read the popliteus muscle is actually really interesting because when we want to unlock the extended knee joint by laterally rotating the femur, its origin is considered on posterior tibia. However, if we want to medially rotate the leg when knee is flexed, we consider the femur as an origin, hope it made sense😂
@@manaral-tamimi5002 that makes sense. origins and insertions can change in closed vs open chain movements
Eversion is caused by the muscles of the lateral compartment, peroneus longus & brevis
Inversion is caused by the synergic muscles tibialis anterior & posterior
Thank you so much..
Awsome as always
great tutorial, thank you so much it is very easely understood,
Thanks!! Very helpful.
so awesome ... keep it up Sir... this is very helpful
You're too good
THANK YOU SO MUCH
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
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
Wow, really? That's so cool
Greatly appreciated!
Really helpful video. In my book though the origin and insertion of Popliteus muscle was reversed 😅. Nevertheless great video. Please keep uploading
This is fantastic, thank you so much!
very helpful.. Tysm
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!!!
really helpful
Thanku so much great
what software / programme are you using for this tutorial. It's very good
zygote body .......
really helpful, nice job, thank you.
Thank you very much!
you r great :) and also genius of anatomy !!! Thanks a lot
it was awesome..
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
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.
Thank you for your help with anatomy:))))))
thank u
Tq so much sir
Thank yooou that's really great !
You're awesome!
yeah me too! the origin is lateral surface of lateral condyle of femur!
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 :)
At 10:39 you mentioned that popliteus rotates the leg laterally but that is wrong, Popliteus rotates the leg medially!
Hey idk if this is too late but basically, the popliteus muscle LATERALLY rotates the FEMUR on the tibia if standing up. However, during sitting down, the popliteus muscle MEDIALLY rotates the TIBIA on the femur.
Amazing vids! What software is this?
This sounds just like a mate of mine (Y) the info is great
Great 🔥🔥🔥🔥🔥🔥🔥🔥
thanks
Some books say the opposite about the insertion and origin of the popliteal muscle. Which is true?
9:41 Isn't the origin of the popliteus muscle lateral condyle of femur and it inserts to proximal tibia?
+YinSuan Hey Yes lateral femoral epicondyle is the origin! He messes up at time! :)
@@adithyanselvam7924 isnt the action medial rotation of the leg or am i mistaken
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!
great !!
Bro you recording on the set of birdbox?
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!
I thought the origin of a muscle was always the closest point of the muscle to the midline. Is this wrong or is the popliteus an exception to the rule?
Can you please tell me which application or program are you using , it will be really helpful.
Good work :)
Popliteus Muscle unlocks the knee at the joint via, Medial Rotation
+C Gray no it is by Lateral rotation of the femur :)
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.
Great
