neu·ri·lem·ma

(nū'ri-lem'ă), Despite etymologic arguments in favor of the alternative spellings neurilema and neurolemma, by far the most usual spelling is neurilemma.
A Schwann cell that enfolds one or more axons of the peripheral nervous system; in myelinated fibers, its plasma membrane forms the lamellae of myelin.

neurilemma

An outer covering of flattened cells that surrounds the MYELIN sheath of the nerve fibres (axons) of the larger peripheral nerves. Neurilemma also covers the axons of non-myelinated nerve fibres. Also known as the sheath of Schwann.

neurilemma

a tough, thin membrane of scleroprotein surrounding the MYELIN SHEATH of myelinated nerve fibres. It is part of the SCHWANN CELL, lying close to the axon, and dips down to the nerve fibre between the Schwann cells, forming the node of Ranvier. See diagram at NEURON.
