Definitions:

Afterpotential

Afterpotential is the transient electrical polarization that follows the action potential in nerve cells or muscle fibers, impacting the cell's excitability.

Depolarization

A decrease in the difference in electrical charge across a cell's plasma membrane, making the inside of the cell less negative compared to the outside.

Hyperpolarization

Hyperpolarization is an increase in a cell's membrane potential, making it more negative and less likely to fire an action potential.

Repolarization

The process of restoring the negative charge inside a neuron or muscle cell after depolarization, preparing it for another action potential.
