ANSWER :
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.
One of the most important functions of the Schwann cell is to myelinate the axons of the PNS. Myelin, which is a fatty layer that insulates the axon, helps to increase the saltatory conduction of the neuron. A myelinating Schwann cell wraps around a single axon.
