Question

Quizplus · Accepted Answer

Myelin consists of layers of lipids and proteins that wrap around an axon to insulate and protect it, improving the speed and efficiency of neural transmission. It is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Myelin is not released from a neuron and does not fill Schwann cells as a form of chromatophilic substance. It is also not produced in response to bacterial infection.
