You are brilliant!!! Very helpuful for understanding correct posture for the violin... things make so much more sense when understanding how the body is built!! Thank you!

I’ve been waiting for this video for 11months 🥳🎉

I cannot express how much this channel helped me ! thank you Sam for putting so much effort on these vids !

I just watched your ventrogluteal injection site video for my T Injections and loved how thorough you were. No more dorsogluteal for me after learning from you. Now I get to learn about the digitorum profundus & the superficialis flexor tendons I sliced through years ago. Very cool channel and you teach so well! 👍🏻 Edit: subscribed!

Very cool , that point about how the fingers don't move completely independently. Big a-Ha moment for me there! All the little interconnections ... THIS is why I watch this channel, all the little easter eggs of wisdom.

Love you sir!!! Long awaited video!!!

Thank you 👏🏻. Just been going through the upper limb muscles and this was helpful.

I love your delivery !!

Thanks for your video. We love it when a lot of the time your video's align with the astro energies. Just had Gemini full moon & Gemini rules the hands, arms, shoulders, lungs and nervous system. Lunar is still in Gemini until tomorrow morning when she goes into Cancer ruler of the chest, breasts & stomach.

Thank youu, ur explanation is eazy to understand

Great video and great knowledge. Thank you

Thanks Sam. I work in A&E and deal with a lot of hand injuries. Your video was invaluable with great detail. I’ve now subscribed.

I cut my thumb nice right on the crease on the bottom. DEEP! I saw fat and other stuff and it bled even 12 hours later before I got it stitched up. I was close to messing up the flexor tendon on my last thumb digit. 2 weeks later I can finally move it again. More feeling is back and more strength. PALM SIDE hand injuries can be dangerous

love your content🎈so helpful

Hiya Sam,,, you may find this amazing, I teach badminton in the pro grades..... i have students come to me and try to smash the shuttlecock as hard as i do and they fail,, no matter how hard they try,,, one major reason they fail is because they hold the handle of the racquet but they stick their "index" finger up the handle a tiny bit.... and i dont,,, i drop my index finger so im holding it like hammer so "index finger down..... my smashes are about 400kph and above and they cant do it.....when they smash they have to raise their elbow because of that index finger up, and i can keep my elbow down, meaning i can rotate waaayyyy quicker get waay more flex and Bam! my smash is quicker..... as soon as they change to finger down ; they can do it..... all because of the tiny placement of an index finger... those finger tendons connect and go up the forearm and change everything in the hit....amazing ..... who'd of thought

Sam I love learning from you

Thanks! When one has”jersey finger”, can the tendon be surgically re-attached? On his first day working in a grocery produce department, our oldest son was handed a box-cutter with no instructions to open boxes. In his case it was the hand holding the cutter that was sliced across the inside fingers. The tendons held but a couple of nerves had to be re-attached. Box-cutters are best avoided.

The splits of the flexor digitorum superficialis tendon to allow the central flexor digitorum profundus tendon passing is such a wonder of nature !

I have Pain on the extenders or whatever on the top of my right hand. If I try to pick something up, it hurts. It’s from overuse in using clippers in the garden. I was hoping he would show some sort of pain relief for it but a good video.

amazing thank you! can you please overview pinky tendons as well

woah amazing

Illuminating the subject so I can understand it!

Thanks 🎉

Thank you! I've been looking for this to understand how to train my fingers to be more independent. To play guitar of course. The guitar playing position means that the wrist can't be straight, so the finger extention tendons are streached while playing, making the finger independece worse. However, different angles of rotation the hand relative to the fretboard can increase or decrease finger independence. Is there a possibility that you could explain why? And more importantly, the best rotation position of the wrist for maximum finger independence while the wrist is flexed? That would be sooooo helpful! Thank you

So I’ve got a question, about 20 years ago I had surgery on my right wrist, but here about a week ago my index finger and thumb went through a bit of what felt like cramping, and now my index finger won’t open all the way. I have gripping power but not opening strength. Any suggestions?

I am from tech background, but loved this anatomy video. to understand what's going in my hand.

i have cut under my thumb and next to the bone knuckle on the palm side, i have struggled to do anythign with the hand - the wound does not seem that bad, but i have increased pain and weakness on the thumb and still p[ins and needles why is this

Watching because I have dupuytren's contracture :( I feel that more than just the tendons in the hand are involved.

🙏

Why there's no subtitle...?

Hey Sam, Great video. Can you tell me where you got your model of upper limb?

What is the yellow vein suppose to b? The deoxygenated blood like suppose to be blue

My left thumb was fully extensor tendon cut..after 2 month of during operation my thumb still cant move to up means signing OK..and my thumb tendon cannot work propely. Why its be like that. Please sir answer me😢

Wait, these skeletons usually have a base. So, That means this skeleton is exactly made after you 😆

Killer joke at the extensor subject!

The thumb is a thing 😂

I,am first yes
