Excitation Contraction Coupling in Skeletal Muscle

In this video, I talk about: the organization of skeletal muscle, the triad junction in skeletal muscle, how excitation-contraction coupling occurs, and how it's terminated. I also talk about CICR (calcium-induced calcium release) and DICR (depolarization-induced calcium release).
