Detailed explanation-1: -Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down.
Detailed explanation-2: -Axons, the wire-like extensions of the neurons, help move the messages, in some cases over many feet, from cell to cell. Oligodendroglia insulate axons, like rubber coating around an electrical wire, to speed up the conduction of information.
Detailed explanation-3: -Myelin is formed by Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS). Each Schwann cell forms a single myelin sheath around an axon.
