Step-by-step solution

Muscle contraction is initiated by a signal sent by the central nervous system via a motor neuron. The correct sequence of events is as follows: First, the neural signal arrives at the axon terminal of the motor neuron (B). This triggers the synaptic vesicles to release the neurotransmitter acetylcholine into the synaptic cleft (A). Acetylcholine then binds to its specific receptors present on the motor end plate (D). This binding generates an action potential in the sarcolemma (C). The action potential spreads thr
