MEDICAL PHYSIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The myelin sheath is a protective membrane that wraps around part of certain nerve cells. Myelin also affects how fast signals travel through those nerve cells.

Detailed explanation-3: -Myelin is a lipid-rich material that surrounds nerve cell axons (the nervous system’s “wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon.

Detailed explanation-4: -Myelin sheath is the protective layer that wraps around the axons of neurons to aid in insulating the neurons, and to increase the number of electrical signals being transferred.
