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 Directly causes cross-bridge detachment 2 Acetylcholinesterase 3 Muscle relaxation 4 Toponin 5 Calcium release by the SR 6 Directly causes cross bridge formation 7 Tropomyosin 8 End Plate Potential 9 Acetylcholine ATP attaches to the myosin head. Triggered by depolarization of the t-tubules. Neurotransmitter released by somatic neurons at the neuromuscular junction. Local sarcolemma depolarization of the neuromuscular junction. Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head. Calcium is actively pumped back into the SR. Regulatory protein that covers the myosin-binding sites of the actin. Degrades acetylcholine in the synapse. Calcium binds to this regulatory protein on the thin filaments.
