Definitions:

Schwann Cells

A type of glial cell in the peripheral nervous system responsible for the formation of myelin sheaths around neuronal axons, aiding in faster signal transmission.

Oligodendroglia

Glial cells in the CNS that myelinate axons.

Myelin

A fatty substance that surrounds the axon of some nerve cells, forming an insulating layer that is essential for the proper functioning of the nervous system, speeding up the transmission of nerve impulses.

Saltatory Conduction

A process whereby nerve impulses jump between gaps in the myelin sheath of neurons, speeding up signal transmission.
