Translationsneurilemma
neurilemma[‚nu̇r·ə′lem·ə] (histology) A thin tissue covering the axon directly, or covering the myelin sheath when present, of peripheral nerve fibers. neurilemma
neurilemma [noor″ĭ-lem´ah] the plasma membrane of a Schwann cell, forming the sheath of Schwann of a myelinated or unmyelinated peripheral nerve. adj., adj neurilem´mal.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. Synonym(s): neurolemma, sheath of Schwann [neuri + G. lemma, husk] neurilemma (no͝or′ə-lĕm′ə, nyo͝or′-)n.1. See Schwann cell.2. The sheath that is formed by a Schwann cell.
neu′ri·lem′mal adj.neu·ri·lem·ma (nūr'i-lem'ă) A cell that enfolds one or more axons of the peripheral nervous system; in myelinated fibers its plasma membrane forms the lamellae of myelin.
Synonym(s): neurolemma, sheath of Schwann. [neuri- + G. lemma, husk]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.Schwann, Theodor, German histologist and physiologist, 1810-1882. Schwann cell unit - a single Schwann cell and all of the axons lying in troughs indenting its surface.Schwann cells - cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves. Synonym(s): neurilemma cellsSchwann tumorSchwann white substance - the lipid material present in the myelin sheath of nerve fibers; the medulla of bones and other organs.schwannoma - Synonym(s): neurilemoma; neuroschwannomasheath of Schwann - a cell that enfolds one or more axons of the peripheral nervous system. Synonym(s): neurilemmaneu·ri·lem·ma (nūr'i-lem'ă) A cell that enfolds axons of the peripheral nervous system.
