| 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 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) |
| abdominal aortic plexus | <anatomy, neurology> An autonomic plexus surrounding the abdominal aorta, directly continuous with the thoracic aortic plexus above and continued inferior to the bifurcation of the aorta as the superior hypogastric plexus. Synonym: plexus aorticus abdominalis. (05 Mar 2000) |
| acromial plexus | A vascular network between the acromion and the skin of the shoulder, formed by anastomoses of the acromial branch of the suprascapular artery with the acromial branch of the thoracoacromial artery. Synonym: rete acromiale, acromial plexus. (05 Mar 2000) |
| annular plexus | A nerve plexus near the corneoscleral junction from which myelinated and unmyelinated nerves pass to the cornea. Synonym: plexus annularis. (05 Mar 2000) |
| anterior coronary plexus | The part of the cardiac plexus that accompanies the coronary arteries on the anterior aspect of the heart. (05 Mar 2000) |
| aortic lymphatic plexus | A plexus of lymph nodes and connecting vessels lying along the lower portion of the abdominal aorta. Synonym: plexus aorticus. (05 Mar 2000) |
| ascending pharyngeal plexus | An autonomic plexus on the artery of the same name, formed of fibres from the superior cervical ganglion. Synonym: plexus pharyngeus ascendens. (05 Mar 2000) |
| Auerbach's plexus | One of two ganglionated neural networks which together form the enteric nervous system. The myenteric (auerbach's) plexus is located between the longitudinal and circular muscle layers of the gut. Its neurons project to the circular muscle, to other myenteric ganglia, to submucosal ganglia, or directly to the epithelium, and play an important role in regulating and patterning gut motility.
