Myelinated axons transmit action potentials more rapidly than unmyelinated axons.

Question

Quizplus · Accepted Answer

Myelin is an insulating layer of fatty material that surrounds axons and acts as an electrical insulator, allowing action potentials to travel more quickly along the axon. In unmyelinated axons, action potentials propagate more slowly and over a shorter distance. Therefore, myelinated axons transmit action potentials more rapidly than unmyelinated axons.
