literally took me 5 minutes to understand the concept.... i thought i will take me an hour to cover this topic.... good thing I stumbled across this video
Thanks a million, short and explicit.🙌🙌🙌
By far the best video ever 😀
it's a crystal clear explanation of sacromere structure.....thank you maam
Thanks, love how you explained this well.
Thank you so much for your video ❤❤❤❤❤
Awesome video!! Thank you so much for posting this, it will help my high school anatomy students understand the components and workings of a sarcomere.

amazing...😍
Ossum explanation💚💚💚
Hey.... Thanks for The amazing videos, but i have one doubt. How does the z dick of a muscle fibre act and shorten the sacromere during contraction as actin filaments from adjacent sarcomeres pull it?
