@ebpanimations Hey guys, I have something unclear about this process, please help me! The question is here, during contraction, a sarcomere shrinks, bringing the z-lines nearer to the center, or m-line. BUT, in the adjacent sarcomere, there exists another force, pulling the z-line in the opposite direction, as consequence of the thick filaments, SO, how does the z-line move, in what direction?
@anikristo1 The key to how it moves is the endpoint forces, which are not sarcomeres. If it can move one or more of the endpoints the z lines will move towards the center of that myofibril. If it were attached to two objects that its forces couldn't overcome it would not move and just create tension.
@ebpanimations Very Very nice animation, very useful, but just one thing : nothing about DHP-r and RyR receptors inside the T-tubules which is a very important step for muscle contraction (especially in miocardiac muscle contraction). Nice job and Thank you! :D
Great video. perfect amount of detail, very clear.
