Definitions:

Oligodendroglia

Glial cells in the central nervous system that produce myelin, a substance that insulates axons to increase the speed at which neural impulses propagate.

Myelin

The fatty substance that surrounds the axon of some nerve cells, forming an insulating layer that speeds up signal transmission.

Oligodendroglial Cells

Oligodendroglial cells are a type of glial cell in the central nervous system responsible for producing and maintaining the myelin sheath, which insulates nerve fiber to enhance signal transmission.

Schwann Cells

Glial cells located in the peripheral nervous system, responsible for the myelination of neuronal axons, thereby increasing the speed of electrical impulses.
