D)The membrane permeability to Na+ decreases.

Question

Quizplus · Accepted Answer

When the resting nerve is stimulated to threshold potential, an action potential fires. This occurs when the depolarization of the neuron reaches a certain threshold, leading to the opening of voltage-gated ion channels and the influx of sodium ions. This triggers a series of events that result in the propagation of the action potential along the neuron.
