Explanation:
Detailed explanation-1: -In the central nervous system, myelin is formed by multipolar glia, oligodendrocytes, that can extend dozens of slender cell processes to ensheath multiple axons simultaneously.
Detailed explanation-2: -Glial cells are the key element for supporting the messages neurons send and receive all over the body. Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon.
