Definitions:

Depolarization

The process by which a cell's membrane potential becomes less negative, leading to an action potential in nerve and muscle cells.

Repolarization

The process by which a cell's membrane returns to its resting potential after depolarization.

Threshold

The minimum level of stimulus needed to activate a physiological response or sensation.

Depolarization

A process where the electrical charge of a cell's membrane becomes less negative, leading to the activation of the cell, often referring to nerve or muscle cells.
