The wave of absolute refractoriness that follows an action potential
A) keeps the action potential from spreading actively back down an axon towards the cell body.
B) increases the firing rate.
C) increases the speed of axonal transmission.
D) produces a second, negative action potential.
E) produces saltatory conduction.

Question

Quizplus · Accepted Answer

The wave of absolute refractoriness prevents the propagation of a new action potential in the opposite direction, ensuring that the signal moves unidirectionally along the axon.
