neurilemman.

Brit.

/ˌnjʊərᵻˈlɛmə/, U.S.

/ˌn(j)ʊrəˈlɛmə/

Origin: A variant or alteration of another lexical item; modelled on a Greek lexical item. Etymon: neurilema n.

Etymology: Alteration of neurilema n. after ancient Greek λέμμα rind, husk (see lemma n.²). Compare French névrilemme (1843 or earlier). Compare also sarcolemma n., myolemma n. at myo- comb. form .

Histology.

1. The sheath of connective tissue around a nerve or nerve fascicle; the perineurium or epineurium. Now rare or disused.

1825 J. M. Good Study Med. (ed. 2) IV. 24 Solid fibres or capillaments of a particular kind, the neurilemma of Bichat.

1851 W. B. Carpenter Man. Physiol. (ed. 2) 224 When the neurilemma has been removed, and the trunk has been separated into its component fasciculi.

1874 A. E. J. Barker tr. H. Frey Histol. & Histochem. of Man 317 The nerves of the brain and spinal cord..become clothed with a delicate envelope at their exit from the nervous centres. This covering receives another addition from the dura mater of connective-tissue bundles in its passage through the latter, and..constitutes what was formerly known as ‘neurilemma’ [Ger. Neurilemm], but which we will designate from henceforth ‘perineurium’.

1888 G. Rolleston & W. H. Jackson Forms Animal Life (ed. 2) 212 The giant fibres are separated from the nerve-cord by the inner neurilemma.

1890 Gray's Anat. (ed. 12) 42 The tubular sheath of the funiculi, called the neurilemma or perineurium.

1930 A. A. Maximow & W. Bloom Text-bk. Histol. xii. 251 Some European writers, like Cajal, apply the term ‘neurilemma’ to the epineurium and not to the sheath of Schwann of the individual fibers.

2. The covering formed by Schwann cells around peripheral nerve fibres (also enclosing the myelin sheath where present). Also called sheath of Schwann, primitive sheath.

1867 Quain's Elements Anat. (ed. 7) I. p. cxliv Some recent writers, believing that the primitive sheath or membranous tube of the nerve-fibre corresponds to the sarcolemma of muscle, have proposed to designate it as the neurilemma, and to use the term perineurium for the coarser sheathing of the nerves and nervous cords.

1874 A. E. J. Barker tr. H. Frey Histol. & Histochem. of Man 307 The existence of an envelope on the nervous tube [sc. fibre] is easily inferred... This neurilemma [Ger. neurilemmige Hülle] may be seen not infrequently as [etc.].

1968 W. Bloom & D. W. Fawcett Textbk. Histol. (ed. 9) xii. 321/1 The myelin is actually part of the Schwann cell, consisting of spirally wrapped layers of its surface membrane... The outer membrane..and the protein-polysaccharide boundary layer on its outer aspect were resolved with the light microscope as a single layer, which has traditionally been called the neurilemma.

1986 A. S. Romer & T. S. Parsons Vertebr. Body (ed. 6) xvi. 540 The cylinder is sheathed by a series of cells that produce a tough, inelastic membrane, the neurilemma.

2002 Jrnl. Submicrosc. Cytol. & Pathol. 34 55 The distance between the immune cell plasma membrane and the neurilemma was 200 nm or less.
