Order the events for muscle contraction: opening of sodium ions channel in sarcolemma calcium ions bind to troponin, shifting tropomyosin, uncovering myosin- binding sites in the actin molecules. motor neuron action potential Acetylcholine release Contraction occurs through the overlapping of thin and thick filaments and muscle fiber shortening. action potential travels down T tubules Sarcoplasmic reticulum releases calcium through voltage-gated channels
