Myelin Sheath

Myelin Sheath

Myelin sheaths are sheaths surrounding the axon of some (myelinated) nerve cells, consisting of concentric layers of myelin, a white fluid fatty substance formed in the peripheral nervous system by the plasma membrane of Schwann cells, and in the central nervous system by ogliodendrocytes. It is interrupted at intervals along the length of the axon by gaps known as nodes of Ranvier. Myelin is an electrical insulator serving to speed the conduction of nerve impulses.
