Place the following events that occur at the vertebrate neuromuscular junction in the correct order.
I-Depolarization of the muscle fiber membrane.
II-Generation of an action potential in the neuron.
III-Stimulation of Ca²⁺ entry into the neuron.
IV-Release of acetylcholine into the synapse.

Question

Quizplus · Accepted Answer

The correct sequence at the vertebrate neuromuscular junction starts with the generation of an action potential in the neuron (II), followed by the stimulation of calcium entry into the neuron (III), which triggers the release of acetylcholine into the synapse (IV), and finally results in the depolarization of the muscle fiber membrane (I).
