Unformatted text preview: ck What event causes depolarization of the sarcolemma at the neuromuscular junction? Student Value Response A. Calcium ions 0% enter the axon B. Calcium ions 0% enter the sarcoplasm from the sarcoplasmic reticulum. C. Acetylcholine 0% is released into the synaptic cleft by exocytosis. D. Acetylcholine 0% binds to postsynaptic receptors on the sarcolemma. E. Na+ moves 0% across the sarcolemma out of the muscle cell. F. Opening of 100% the chemicallygated sodium channels. G. Opening of 0% the voltagegated sodium channels. H. Opening of 0% potassium channels. I. Binding of 0% calcium ions to Troponin C. 0% J. Uptake of ATP by the myosin heads. K. Attachment 0% of actinmyosin crossbridges and swiveling of the myosin heads. Score: 39. Correct Answer 0/1 Voltage gated Na+ channels open.
