Question

Quizplus · Accepted Answer

The myelin sheath is a white, fatty layer that surrounds many nerve fibers. It is made up of glial cells (specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system) and serves to insulate the nerve fibers, increasing the speed at which electrical impulses (neural messages) are transmitted along the axon of the neuron.
