The primary feature of a neuron that prevents the action potential from traveling back from where it just passed is the ____.
A) concentration gradient
B) refractory period
C) sodium potassium pump
D) phospholipid bilayer

Question

Quizplus · Accepted Answer

The refractory period is the time during which the neuron is not able to generate another action potential. This is due to the fact that the sodium channels are inactivated and cannot be reactivated until the membrane potential returns to its resting state. Therefore, the refractory period prevents the action potential from traveling back in the opposite direction.
