Propagation speed refers to how quickly an action potential travels along an axon. It can vary depending on factors such as myelination, axon diameter, and temperature.

Saltatory Conduction: A process where action potentials "jump" from one node of Ranvier (the gaps in myelin) to another, increasing propagation speed.
Axon Diameter: The width or thickness of an axon impacts how fast an action potential can move; wider axons allow for quicker propagation.
