In this video we review how the processes that lead to contraction and relaxation of the skeletal muscle occur, it is important to analyze how the release of calcium occurs and what is its function, what is the function of ATP and at what time is the release energy to slide the thin filament, it is also important to remember that proteins are involved in removing calcium from the intracellular medium.
