Quizplus · Accepted Answer

The myelin sheath is a fatty layer that surrounds the axons of many neurons. It acts as an insulator and increases the speed at which electrical impulses (action potentials) are transmitted along the axon. This is because it enables saltatory conduction, where the electrical impulse jumps from one node of Ranvier (gaps in the myelin sheath) to the next, significantly speeding up signal transmission.
