What term refers to the return of polarity towards resting potential after depolarization?

Repolarization is the term used to describe the process where the membrane potential of a neuron returns to its resting state after depolarization has occurred. During depolarization, the cell membrane becomes more positively charged due to the influx of sodium ions. Repolarization occurs when potassium ions exit the neuron, bringing the membrane potential back down towards the resting potential, which is typically around -70 mV. This process is crucial for the proper functioning of neurons and allows them to return to a state where they are ready to be re-excited for the next action potential.

Other terms in the options have distinct meanings. Hyperpolarization occurs when the membrane potential becomes more negative than the resting potential, usually due to excessive efflux of potassium ions or influx of chloride ions. Depolarization refers to the initial change in the membrane potential that makes the inside of the cell more positive. Restoration is a more general term and does not specifically refer to the specific physiological process following depolarization.Thus, the proper term that refers specifically to the return of polarity towards resting potential after depolarization is indeed repolarization.
