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.

Node of Ranvier

Gaps in the myelin sheath of nerve fibers where the axonal membrane is exposed to the extracellular space, facilitating rapid signal transmission.
