According to the Text, Why is the Refractory Period of a Neuron's

Question

According to the text, why is the refractory period of a neuron's plasma membrane important?
A) because it initiates an action potential
B) because it ensures that an impulse will travel in a one-way direction
C) because it ensures that the threshold potential will be reached
D) because it establishes the resting potential

Accepted Answer

The refractory period of a neuron's plasma membrane is important because it ensures that an impulse will travel in a one-way direction, preventing the backward movement of the action potential and thus contributing to the unidirectional flow of neural signals.
