What is myelin?

Human BiologyNervous System

Quick Answer

Myelin is a fatty insulating layer around many nerve fibers. It helps electrical signals travel faster and more efficiently.

The Full Story

Myelin wraps around the axons of many neurons, forming an insulating sheath that speeds nerve conduction. In the central nervous system, myelin is made by oligodendrocytes; in the peripheral nervous system, it is made by Schwann cells. Damage to myelin can disrupt signaling and cause neurological problems. Myelination is crucial for normal development and efficient communication in the nervous system.

Key Facts

1.Myelin insulates nerve fibers
2.Oligodendrocytes make CNS myelin
3.Schwann cells make peripheral myelin
