The refractory period is when:
A) a ganglion cell generates an action potential
B) a cell returns to its resting potential
C) hyperpolarization takes place
D) depolarization takes place

Question

Quizplus · Accepted Answer

The refractory period refers to the time period immediately after the generation of an action potential during which the neuron is unable to generate another action potential. During this period, the neuron returns to its resting potential before it can be depolarized again. Therefore, option B, which states that the refractory period is when a cell returns to its resting potential, is the best choice.
