Immediately after an action potential passes along an axon, it is not possible to generate a second action potential. Thus, we state that the membrane is briefly ________.
A) hyperexcitable
B) refractory
C) fully depolarized
D) above threshold
E) at the equilibrium potential

Question

Quizplus · Accepted Answer

The refractory period refers to the brief time period immediately following an action potential during which the membrane is unable to generate another action potential, even if a stimulus of sufficient strength is applied. This occurs due to the inactivation of sodium channels and the slow repolarization of the membrane potential.
