The absolute refractory period assures
A) prolonged depolarization during the action potential.
B) completion of repolarization before another action potential.
C) that no after-potential occurs.
D) reversal of the direction of propagation of the action potential.
E) that the stimulus is strong enough to elicit a response.

Question

Quizplus · Accepted Answer

The absolute refractory period is the time during which a second action potential cannot be initiated, no matter how strong a stimulus is applied. This ensures that each action potential is followed by a period of repolarization before another action potential can occur, preventing the possibility of continuous, uncontrolled firing of the neuron.
