Relacionar Columnas Skeletal Muscle ContractionVersión en línea Match the various steps of a skeletal muscle contraction with the descriptions of that action. por Lindsay Spielman 1 End Plate Potential 2 Acetylcholine 3 Toponin 4 Directly causes cross bridge formation 5 Calcium release by the SR 6 Tropomyosin 7 Muscle relaxation 8 Directly causes cross-bridge detachment 9 Acetylcholinesterase Neurotransmitter released by somatic neurons at the neuromuscular junction. Degrades acetylcholine in the synapse. Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head. Calcium binds to this regulatory protein on the thin filaments. Calcium is actively pumped back into the SR. Triggered by depolarization of the t-tubules. Local sarcolemma depolarization of the neuromuscular junction. ATP attaches to the myosin head. Regulatory protein that covers the myosin-binding sites of the actin.
