Opening of voltage-gated sodium channels in the membrane of a neuron results in
A) depolarization.
B) repolarization.
C) hyperpolarization.
D) increased negative charge inside the membrane.
E) myelination.

Question

Quizplus · Accepted Answer

Opening of voltage-gated sodium channels in the membrane of a neuron results in depolarization, which is the process of the membrane potential becoming less negative and more positive. This occurs because sodium ions rush into the cell, causing an influx of positive charge.
