Depolarization

The process in which a cell's membrane potential becomes less negative, moving towards zero, typically initiating nerve impulses or muscle contractions.

Resting Potential

Electrical charge across the insulating cell membrane in the absence of stimulation; a store of potential energy produced by a greater negative charge on the intracellular side relative to the extracellular side.

Hyperpolarization
