MEDICAL PHYSIOLOGY

Detailed explanation-1: -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-2: -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-3: -Most of the axons in the central nervous system are wrapped in myelin, a substance rich in lipids (fatty substances) and proteins. Like the coating around an electrical wire, myelin insulates and protects the axon and helps speed nerve transmission.
