Neuromuscular Junction (9)

*EDIT* - The two 'muscle cells' I describe are myofibrils, NOT muscle cells. (One muscle cell will have one axon innervating it, and that action potential will be sent down T-Tubules to release calcium into the neighboring myofibrils). This video is all about the physiology of the neuromuscular junction. With an understanding that we need calcium ions in the muscle fibers in order for sarcomeres to contract, Mr. Jackson takes us through all the steps from neuron action potential to muscle contraction.
