Question

Quizplus · Accepted Answer

The myelin sheath is a fatty tissue that wraps around the axon of some neurons. This sheath acts as an insulator, speeding up the neural message travelling down the axon because the action potential is able to jump from one node of Ranvier (a gap in the myelin sheath) to the next, rather than having to travel the entire length of the axon. This phenomenon is known as saltatory conduction.
