After a neuron has sent a nerve pulse, it has to rest for a few milliseconds, a timeframe referred to as
A) an action potential.
B) an absolute refractory period.
C) a graded potential.
D) an anion.

Question

Quizplus · Accepted Answer

The absolute refractory period is a brief period following the generation of an action potential during which the neuron is incapable of generating another action potential. This is due to the fact that the voltage-gated sodium channels are inactivated, which prevents the influx of sodium ions that is necessary for the depolarization phase of an action potential. During this time, the neuron is said to be "resting" or "recovering," which allows it to reset its voltage-gated channels and prepare for the next action potential. Neither A, C, nor D accurately describe this timeframe.
