- Number six and it's the HAND. Just an incredible piece of machinery - from gripping and lifting to handling tiny objects - the secret to the hand's versatility and strength lies in the intricacy of it anatomy, with long tendons bringing power and small muscles bringing finesse. Do have a good look at your own hands while you watch this video. Next time I'll be talking about some of the nerves that allow you to control all these actions - and some blood vessels too.

We always learn new information with Prof. Dr. Alice Roberts. Thanks Prof Alice Roberts.
Goodness, gracious. The things we take for granted about our own bodies are wonderful when explained in such a sympathetic way. Kudos Alice.
Professor Alice,
Thank you very much for that valuable lesson. If it is possible could you please
give a lesson about the Leg and particularly the knee/ articulations.
Thank You!
Excellent stuff, lovely to see. As a carpal tunnel syndrome sufferer it was nice to see exactly what the carpal tunnel was!
Wow our hands are so complex and fantastic. This series of videos is great, thank you
Thank you for the video, very interesting. If you put the videos into a playlist it will be easier to share and useful to keep them in order. Thanks again, you're awesome.
Aidan McGill Thank you - I will try to work out how to do that!
Fascinating
Awesome, Beautifully explained. Thank you Professor
These videos have been fascinating, there is so much to learn about our own bodies & these videos give me a much better understanding of what's going on beneath the skin.
Q, In general (not including actual ailments) what causes joints to crack in the unpleasant manner that they often do?
Brilliant as always,thanks so much!! :)
Thanks again
The human body is amazing and I bet most people don't give it a second thought to what lies beneath and how it all works. How do you hold all this knowledge in your head.
John Barnes Too many years of teaching it! It’s like “the knowledge” - a mental map of the body.
Alice Roberts it's impressive you manage to store it all, mine is like a sponge that someone is constantly squeezing all the knowledge out of it , very annoying sometimes.
8:39 -- I absolutely cannot move my thumb like that without my index finger also flexing. I've been a musician my entire life, a pianist, so it's not like I lack control over my hands. But the way your hand looks at 8:42 is literally something I cannot do on either hand. What on Earth could cause that?
Also, as a musician, I've got to ask: why can't the ring finger extensor tendon work as well as the others? The fact that it can't has been the bane of many a musician's existence, and I really would love to know from an anatomical point of view exactly why that finger can't extend back nearly as well as the other, individually.
Did you put this up twice? im sure I saw something about hands appear the other day!
Which app are you using
I have heard that technically there are no muscles in the fingers,only in the hand, but arent there something called a muscle that keeps hair standing on end? or am I going crazy
Phonotical Yes, you’re right! So here’s the pedantic, finicky truth: there are no muscle bellies of skeletal muscles in the fingers - but of course their tendons run into the fingers. But there is plenty of smooth muscle - those tiny arrector pili muscles you quite rightly mentioned - and smooth muscle in artery walls too!
@@aliceroberts4107 wow, muscle in arteries?!
Circulation and why someones hands are cold but others are not..
