A covering or wrapper of a nerve. Also called neurilemma, this thin membrane enwraps the myelin layers of some myelinated nerve fibers, especially peripheral ones, or the extensions of certain unmyelinated nerve fibers.

thin membranous sheath around a nerve fiber

Greek neuron = nerve, and lemma = peel or rind; hence, the covering layer of a nerve.

The outer sheath of a peripheral nerve fiber formed by a Schwann cell (i.e., its myelin wrapping).

Delicate nucleated outer sheath of a nerve cell; sheath of Schwann.

The delicate membranous covering of a nerve fiber. Also called sheath of Schwann.

the peripheral, nucleated cytoplasmic layer of the neurolemmocyte (Schwann cell); also called sheath of Schwann

Outermost covering of nerve fiber; also spelled neurilemma

Neurolemma (also neurilemma and sheath of Schwann) is the outermost layer of nerve fibers in the peripheral nervous system. It is a nucleated cytoplasmic layer of Schwann cells that surrounds the myelin sheath of axons.
