Definitions:

Depolarization

A decrease in membrane potential that makes the interior of a cell less negative compared to the outside, crucial for nerve impulse transmission and muscle contractions.

Repolarization

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

Afterpotential

Afterpotential represents the change in membrane potential that follows an action potential in nerve cells, affecting the cell's responsiveness to subsequent stimuli.

Threshold

The point or level at which a stimulus is of sufficient intensity to begin to produce an effect.
