What is Schwann cells?

Schwann cell, also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century.

How do Schwann cells work?

The way Schwann cells work is because Schwann cells are a variety glial cell that keep peripheral nerve fibres (both myelinated and un myelinated) alive. In myelinated axons, Schwann cells form the myelin sheath.
