Myelin sheath: The myelin sheath is

The myelin sheath is a greatly extended and modified plasma membrane wrapped around the nerve axon in a spiral fashion [1]. The myelin membranes originate from and are a part of the Schwann cells in the peripheral nervous system (PNS) and the oligodendroglial cells in the central nervous system (CNS) (see Chap. 1). Explore the structure, function, and importance of myelin in the brain, its role in neural communication, and its impact on brain health and disorders. Learn about the structure, function, and clinical aspects of myelin sheaths, the insulating layer around axons in the nervous system. Find out how myelination occurs in the central and peripheral nervous system, and what happens in demyelinating diseases. Myelin is a multilamellar membrane that surrounds axons in the vertebrate nervous system. Properly functioning myelin is essential for the rapid conduction of nerve impulses, and it metabolically supports axonal integrity. Emerging evidence ...
