Definitions:

Membrane Potential

The voltage across a cell's plasma membrane, representing a difference in electrical charge inside and outside the cell.

Afterpotential

The transient change in membrane potential that occurs following a nerve impulse, affecting neuron excitability.

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.
