Reference Entry
A definition of the term "Schwann cell" is presented. It refers to one of the cells of the peripheral nervous system that form the myelin sheath and neurilemma of peripheral nerve fibers. The Schwann cells grow around the nerve fiber, forming concentric layers of cell membrane in the embryo. The cytoplasm and nuclei of the Schwann cells, external to the myelin sheath, forms the neurilemma.
