Regulatory protein that covers the myosin-binding sites of the actin. Calcium is actively pumped back into the SR. Degrades acetylcholine in the synapse. Local sarcolemma depolarization of the neuromuscular junction. Calcium binds to this regulatory protein on the thin filaments. Triggered by depolarization of the t-tubules. ATP attaches to the myosin head. Neurotransmitter released by somatic neurons at the neuromuscular junction.
