Detailed explanation-1: -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-2: -Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon. This myelination, as it is called, can greatly increase the speed of signals transmitted between neurons (known as action potentials).

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: -Oligodendrocytes wrap axons in an insulating material, called myelin, that speeds up the electrical signals. The myelination process is essential for normal nervous system function and it may contribute to learning and skill development.

Detailed explanation-5: -Myelin sheath function Since the myelin sheath surrounds the axon, one of its functions is to separate the axon from surrounding extracellular components. Its main function, however, is to insulate the axon and increase the velocity of action potential propagation.
