After the stimulus ends, the cell returns to its resting charge; what is this process called?

Explanation:
Repolarization is the phase where the membrane potential returns toward the negative resting value after depolarization. When an action potential occurs, Na+ channels open and the inside of the cell becomes more positive. As the stimulus ends, Na+ channels inactivate and voltage-gated K+ channels open, allowing K+ to flow out. The outward movement of positive charge makes the inside more negative again, bringing the membrane potential back toward the resting level. Sometimes this is followed by a brief hyperpolarization before the mechanisms restore the true resting potential.
