| Ranvier, Louis | <person> French pathologist, 1835-1922. See: Ranvier's crosses, Ranvier's disks, Ranvier's node, Ranvier's plexus, Ranvier's segment. (05 Mar 2000) |
|---|---|
| Ranvier, Louise Antoine | <person> Was a Physician and Histologist. Professor in the College of France, Paris. Ranvier's Nodes - short specialised interruptions in the myelin sheath occurring along myelinated nerve fibres. Responsible for saltatory conduction. Lived: 1835-1922. B. Lyons, 1835, d. 1922. (05 Dec 1998) |
| Ranvier's crosses | Black or brown figures in the shape of a cross, marking Ranvier's nodes in the longitudinal section of a nerve stained with silver nitrate. (05 Mar 2000) |
|---|---|
| Ranvier's disks | Tactile nerve endings, of cupped disklike form, in the skin. (05 Mar 2000) |
| Ranvier's node | A short interval in the myelin sheath of a nerve fibre, occurring between each two successive segments of the myelin sheath; at the node, the axon is invested only by short, finger-like cytoplasmic processes of the two neighboring Schwann cells or, in the central nervous system, oligodendroglia cells. See: myelin sheath. (05 Mar 2000) |
| ranvier's nodes | Regularly spaced gaps in the myelin sheaths of peripheral axons. Ranvier's nodes allow saltatory conduction, that is, jumping of impulses from node to node, which is faster and more energetically favourable than continuous conduction. (12 Dec 1998) |
| Ranvier's plexus | A subbasal stroma plexus of the cornea. See: stroma plexus. (05 Mar 2000) |
| Ranvier's segment | The portion of a myelinated nerve fibre between two successive nodes. Synonym: interannular segment, internode, Ranvier's segment, segmentum internodale. (05 Mar 2000) |
| node of Ranvier | <anatomy, physiology> A region of exposed neuronal plasma membrane in a myelinated axon. Nodes contain very high concentrations of voltage gated ion channels and are the site of propagation of action potentials by saltatory conduction. (18 Nov 1997) |
| Baudelocque, Louis | <person> French obstetrician, 1800-1864. See: Baudelocque's operation. (05 Mar 2000) |
| Vaquez, Louis | <person> French physician, 1860-1936. See: Vaquez' disease. (05 Mar 2000) |
| Malassez, Louis | <person> French physiologist, 1842-1910. See: Malassezia, Malassez' epithelial rests. (05 Mar 2000) |
| Gehrig, Henry Louis | <person> U.S. Baseball player; 1903-1941, victim of Lou Gehrig's disease. See: Lou Gehrig's disease. (05 Mar 2000) |
| Pasteur, Louis | <person> A French chemist and biologist who founded the field of bacteriology and developed the germ theory. He also invented pasteurisation and created the first vaccines against anthrax and rabies. Lived: 1822-1895. (09 Oct 1997) |
| Chenais, Louis | <person> French physician, 1872-1950. See: Cestan-Chenais syndrome. (05 Mar 2000) |
| Ripault, Louis | <person> French physician, 1807-1856. See: Ripault's sign. (05 Mar 2000) |
| Rocher, Henri Gaston Louis | <person> French surgeon, *1876. See: Rocher's sign. (05 Mar 2000) |
