At the vertebrate neuromuscular junction,correctly order the following reactions.
I-Muscle fiber membrane is depolarized.
II-Action potentials are generated in the neuron.
III-Stimulation of the entry of Ca²⁺ into the neuron.
IV-Release of acetylcholine into the synapse.

Question

Quizplus · Accepted Answer

The correct order is: Action potentials are generated in the neuron (II), which stimulates the entry of Ca²⁺ into the neuron (III), leading to the release of acetylcholine into the synapse (IV), and finally, the muscle fiber membrane is depolarized (I).
