An action potential does not restimulate the adjacent membrane that was previously depolarized because
A)Stimulation is inhibited by the myelin sheath
B)It is impossible for an action potential to be propagated along an axon toward the nerve cell body
C)The resting membrane potential of the axon is too high
D)The resting membrane potential of the axon is too low
E)This area of membrane is absolutely refractory to depolarization

Question

Quizplus · Accepted Answer

The absolute refractory period is a brief period following the initiation of an action potential in which no amount of stimulation can cause another action potential to be generated. This is due to the fact that the voltage-gated sodium channels responsible for generating an action potential are inactivated during this time and cannot be reopened until the membrane potential has returned to its resting level. Therefore, even if a stimulus were applied during this period, the adjacent membrane that was previously depolarized cannot be restimulated.
