Detailed explanation-1: -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.

Detailed explanation-2: -Schwann cells, specialized neuroglia cells, produce myelin sheath, which acts as insulation along the axon. Most mammalian neurones are coated in a whitish, fatty layer called the myelin sheath (not part of the neuron.) It insulates the nerve fibers to prevent signal loss or crossing of signals.

Detailed explanation-3: -Schwann cells (SCs) are the main glial cells of the peripheral nervous system which wrap around axons of motor and sensory neurons to form the myelin sheath.

Detailed explanation-4: -Schwann cells are derived from the neural crest and play crucial roles in the maintenance and regeneration of the motor and sensory neurons of the peripheral nervous system (PNS). They are mainly required for insulating (myelinating) and supplying nutrients to individual nerve fibers (axons) of the PNS neurons.

Detailed explanation-5: -Answer and Explanation: Schwann cells form what’s known as a myelin sheath which wraps around a nerve fiber to insulate it.
