Unformatted text preview: ult of threshold depolarization at the neuromuscular junction, what happens on the adjacent sarcolemma? Student Response A. Calcium ions enter the axon B. Calcium ions enter the sarcoplasm from the sarcoplasmic reticulum. C. Acetylcholine is released into the synaptic cleft by exocytosis. D. Acetylcholine binds to post-synaptic receptors on the sarcolemma. E. Na+ moves across the sarcolemma into the muscle cell. F. Opening of the chemically-gated sodium channels. G. Opening of the voltage-gated sodium channels. H. I. J. K. Score: Opening of potassium channels. Binding of calcium ions to Troponin C. Uptake of ATP by the myosin heads. Attachment of actin-myosin crossbridges and swiveling of the myosin heads. 0.5/0.5 1. voltage-gated ion channels Value 0% 0% 0% 0% 0% 0% 100% 0% 0% 0% 0% Feedback Threshold depolarization will result in an action potential when it occurs at: Student Response A. chemically-gated ion channels only B. voltage-gated ion channels only Value 0% 100% C.
