Saltatory Conduction



Animation showing smooth conduction of the action potential in unmyelinated neuron and saltatory (or jumping) conduction in a myelinated axon. Saltatory conduction is faster than smooth conduction. Some typical action potential velocities are as follows:

Fiber Diameter AP Velocity
Unmyelinated 0.2-1.0 micron 0.2-2 m/sec
Myelinated 2-20 microns 12-120 m/sec
