Myelin is present in the central nervous system (CNS) and peripheral nervous system (PNS); however only the central nervous system is affected by MS. CNS myelin is produced by special cells called oligodendrocytes.PNS myelin is produced by Schwann cells.The two types of myelin are chemically different, but they both perform the same function â to promote efficient transmission of a nerve impulse along the axon.ach neuron is made up of a cell body and an axon (the extension of the cell body that carries messages). Most of the axons in the central nervous system are wrapped in myelin, a substance rich in lipids (fatty substances) and proteins.
