Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.
