Tropomyosin
Toponin
Acetylcholinesterase
Calcium release by the SR
End Plate Potential
Muscle relaxation
Directly causes cross-bridge detachment
Directly causes cross bridge formation
Acetylcholine
Degrades acetylcholine in the synapse.
ATP attaches to the myosin head.
Calcium binds to this regulatory protein on the thin filaments.
Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head.
Local sarcolemma depolarization of the neuromuscular junction.
Triggered by depolarization of the t-tubules.
Regulatory protein that covers the myosin-binding sites of the actin.
Calcium is actively pumped back into the SR.
Neurotransmitter released by somatic neurons at the neuromuscular junction.
