Schwann cells are the supporting cells of the PNS. Like oligodendrocytes schwann cells wrap themselves around nerve axons, but the difference is that a single schwann cell makes up a single segment of an axon's myelin sheath.
Schwann cells and oligodendrocytes make the myelin sheaths of the peripheral nervous system (PNS) and central nervous system (CNS), respectively. Their myelin sheaths are structurally similar, consisting of multiple layers of specialized cell membrane that spiral around axons.
