Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head. Calcium binds to this regulatory protein on the thin filaments. Regulatory protein that covers the myosin-binding sites of the actin. Neurotransmitter released by somatic neurons at the neuromuscular junction. Triggered by depolarization of the t-tubules. Degrades acetylcholine in the synapse. ATP attaches to the myosin head. Local sarcolemma depolarization of the neuromuscular junction.
