Only Myelinated Axons Have Saltatory Conduction

Question

Only myelinated axons have saltatory conduction.

Accepted Answer

Saltatory conduction is the rapid propagation of action potential along a myelinated axon, as the electrical signal "jumps" from one node of Ranvier (the unmyelinated gap between myelin sheaths) to another, rather than traveling the full length of the axon. Unmyelinated axons do not have this mechanism for rapid conduction.
