Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head. Calcium binds to this regulatory protein on the thin filaments. ATP attaches to the myosin head. Neurotransmitter released by somatic neurons at the neuromuscular junction. Degrades acetylcholine in the synapse. Calcium is actively pumped back into the SR. Triggered by depolarization of the t-tubules. Local sarcolemma depolarization of the neuromuscular junction.
