Detailed explanation-1: -To act as an electric insulator, the myelin sheath is formed as a multilamellar membrane structure by the spiral wrapping and subsequent compaction of the oligodendroglial plasma membrane around central nervous system (CNS) axons.
Detailed explanation-2: -The central function of oligodendrocytes is to generate myelin, which is an extended membrane from the cell that wraps tightly around axons. Due to this energy consuming process and the associated high metabolic turnover oligodendrocytes are vulnerable to cytotoxic and excitotoxic factors.
Detailed explanation-3: -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.
Detailed explanation-4: -oligodendrocyte, a type of neuroglia found in the central nervous system of invertebrates and vertebrates that functions to produce myelin, an insulating sheath on the axons of nerve fibres.
Detailed explanation-5: -The primary function of oligodendrocytes is to make myelin sheath around the axons in the white matter of CNS. They do this by wrapping around the axons and forming layers of the membrane around them.
