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 Acetylcholinesterase 2 Directly causes cross bridge formation 3 Tropomyosin 4 Muscle relaxation 5 Toponin 6 End Plate Potential 7 Directly causes cross-bridge detachment 8 Acetylcholine 9 Calcium release by the SR ATP attaches to the myosin head. 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. Triggered by depolarization of the t-tubules. Local sarcolemma depolarization of the neuromuscular junction. Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head. Neurotransmitter released by somatic neurons at the neuromuscular junction. Calcium is actively pumped back into the SR.
