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