How do muscles contract?

[@daniellekeller4599]

Great explanation! I am in a A&P class and just watching this video made the whole process just click.! Thank you!!!

[@kierstysutton8263]

BEST. VIDEO. EVER. I understood everything so well! I loved the visuals that were used as well. She explained it so I, a very beginner, could understand!! Thank youuuuu

That was awesome. I really didn't know that contracting muscle includes such complex and long way tasks. It really helped me. Thanks a lot. I wish that I could use the mechanism of contraction of muscles to make a powerful actuator.

Wish i had found this video 2yrs ago

This was super helpful. Thanks!

Why did Kon have super strong legs? He had "mod cells". (Only Bleach fans will get this joke...)

I am curious how much force do the myosin heads exert on contraction? and would my conclusion that the strength of a muscle scales with the cross-section and the distance with the length? I am wondering about possible techniques for mechanical muscles. normally you see the pneumatic ones, where a tube is pressurized in order to increase its width, so that the length shortens, ergo, contraction. but a huge downside is that method is not really a muscle, because you generate the force elsewhere. Based on this video I am wondering that it might be possible to manufacture the interlacing of the thick and thin filaments as metal on some kind of plastic substrate. then "roll" those sheets up to get your fiber, bundle those again. thereby fully minicing what mother nature invented for us. I am however afraid I am thinking to romantically about this. and that the mechanical solution is not nearly capable of exerting as much force as an organic muscle.

How is ATP converted to ADP during muscle contraction?

😳 I’m so glad I’m not a doctor

You're amazing

Where does all the calcium waste go???

[@sheerin_jjk1322]

Thanku

[@khkgkgkjgkjh6647]

You failed to explain how chemical energy converts to mechanical energy. Where does the physical force for muscle contraction come from?

[@gumanelson2007]

So nothing is understood

[@ClarkWhite81]

Yup
