@@bytesizemed Yes,my question were getting wrong regarding this topic but after this it never went wrong thanks to you☺️

[@user-qo1sh8vw9u]

loved the way you teach........:) 😘😘😘😘😘😘😘😘😘

[@mohammedamaanshaikh5187]

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?
