Ranviern.

Brit.

/ˈrɒ̃vɪeɪ/, U.S.

/ˈrɑnviˌeɪ/

Origin: From a proper name. Etymon: proper name Ranvier.

Etymology: < the name of Louis Antoine Ranvier (1835–1922), French histologist, who described the structures (as anneau constricteur and étranglement annulaire) in 1871 ( Comptes rendus hebd. de l'Acad. des Sci. 73 1171) and 1872 ( Arch. de physiol. normale et pathol. 4 129).

Histology.

node of Ranvier n. (also Ranvier node, Ranvier's node) any of the gaps in the myelin sheath that occur between neighbouring Schwann cells or oligodendrocytes along a myelinated nerve fibre.

1876 M. Foster & J. Langley Course Elem. Pract. Physiol. 58 Observe..the break in the medullary sheath (Ranvier's node) between each two nuclei.

1885 Encycl. Brit. XIX. 23/2 The medullary sheath shows at certain intervals interruptions called the ‘nodes of Ranvier’.

1912 J. D. Lickley Nerv. Syst. ii. 11 On the outside of the medullary sheath..is a thin structureless membrane known as the neurilemma... It is a continuous sheath and is not interrupted at the nodes of Ranvier.

1950 Exper. Cell Res. 1 310 Membranous sheaths..interrupted at periodic intervals of 1–3 mm by constrictions or Ranvier nodes.

1979 Jrnl. Amer. Med. Assoc. 23 Mar. 1248/3 This resulted in displacement and obstruction of Ranvier's nodes, producing a conduction block.

2002 T. Shimoda Fourth Treasure (2003) 153 The sheath is not continuous; small gaps called nodes of Ranvier act like booster stations, increasing the strength of the signal.
