Definitions:

Action Potential

A temporary reversal of electrical charge across a cell membrane, leading to the transmission of nerve impulses.

Myelinated

Refers to axons that are covered with a fatty sheath called myelin, which increases the speed at which electrical impulses propagate along the nerve cell.

Axon Diameter

The thickness of the axon, which influences the speed of nerve impulse conduction.

Action Potential Speed

The rate at which an action potential, or a short-lasting event of electrical charge reversal in a neuron, travels along a nerve fiber.
