Definitions:

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.

Saltatory Conduction

The process by which nerve impulses jump between the nodes of Ranvier in myelinated neurons, speeding up signal transmission.
