Explanation:
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: -Again, depending on the location within the body, these structures can be covered in sheaths of an insulating material known as myelin. Based on the presence or absence of the myelin sheath, axons are distinguishable into myelinated and non-myelinated axons.
