What do Schwann cells do?

Explanation:
Schwann cells are the myelinating glia of the peripheral nervous system. They wrap around a segment of a peripheral axon to form the myelin sheath, insulating the axon and speeding up electrical signals through saltatory conduction. In the CNS, myelination is done by oligodendrocytes, not Schwann cells, which helps distinguish the two. A Schwann cell typically myelinates a single axon segment, and these cells also provide metabolic support and assist in regeneration after injury in the PNS. Because their main role described here is producing myelin in the peripheral nervous system, that is the best fit.
