In case of peripheral nerves the myelin sheath is formed by the Schwann cells and in the central nervous system the. However whilst Schwann cells myelinate axons of the PNS the oligodendrocytes provide myelination to axons in the central nervous system CNS. A Schwann cell becomes apposed to an axon and envelopes it in a trough.

Myelin itself forms by the spiral wrapping around an axon of an enormously expanded glial plasma membrane that then compacts. Axons in the peripheral nervous system are myelinated by special supporting cells called Schwann cells which wrap themselves tightly around the Axon in Jelly roll fashion so that when the process is completed a tight core of plasma membrane material called the myelin.
