Propagation Speed

Definition

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.

Related terms

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.

Temperature:

Higher temperatures increase molecular movement and enhance propagation speed.
