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