During the resting potential,sodium channels open when:
A) there is an increase in sodium-potassium pump activity.
B) an inhibitory postsynaptic potential occurs.
C) the local potential becomes depolarized.
D) the local potential becomes hyperpolarized.

Question

Quizplus · Accepted Answer

During the resting potential, sodium channels open in response to depolarization of the local potential. This means that when the inside of the neuron becomes less negative compared to the outside (depolarization), it triggers the opening of sodium channels, allowing sodium ions to flow into the cell, further depolarizing it.
