| vasomotor centre | Diffuse area of the reticular formation in the lateral medulla containing neurons that control vascular tone; consists of separate vasodepressor and vasopressor areas. (05 Mar 2000) |

| vasomotor | 1. <physiology> Affecting the calibre of a vessel, especially of a blood vessel. 2. Any element or agent that effects the calibre of a blood vessel. Origin: L. Motor = mover (18 Nov 1997) |
|---|---|
| vasomotor angina | Angina pectoris in which the breast pain is comparatively slight, but pallor followed by cyanosis, and coldness and numbness of the extremities, are marked. Synonym: angina spuria, angina vasomotoria, pseudangina, pseudoangina, reflex angina, vasomotor angina. (05 Mar 2000) |
| vasomotor ataxia | A form of autonomic ataxia causing irregularity in the peripheral circulation, marked by alternations of pallor and suffusion, due to spasm of the smaller blood vessels. (05 Mar 2000) |
| vasomotor epilepsy | Episodes of autonomic dysfunction presumably due to diencephalic irritation. Synonym: diencephalic epilepsy, vasomotor epilepsy, vasovagal epilepsy. (05 Mar 2000) |
| vasomotor fibres | Postganglionic visceral efferent fibres innervating the smooth muscles of vessel walls. (05 Mar 2000) |
| vasomotor imbalance | A lack of balance between sympathetic and parasympathetic nervous systems, especially in relation to the vasomotor disturbances. Synonym: vasomotor imbalance. (05 Mar 2000) |
| vasomotor nerve | <anatomy, nerve> A motor nerve effecting or inhibiting contraction of the blood vessels. (05 Mar 2000) |
| vasomotor neurosis | A group of trophic disorders in which pathological changes occur in blood vessels, often due to autonomic nervous system dysfunction; includes Raynaud's disease, acrocyanosis, erythromelalgia, Buerger's disease, causalgia, and trench foot; archaic concept. Synonym: angioneurosis, vasoneurosis. (05 Mar 2000) |
| vasomotor paralysis | A mild degree of vasoparalysis. Synonym: angioparesis, vasomotor paralysis. Origin: vaso-+ G. Paresis, weakness (05 Mar 2000) |
| vasomotor rhinitis | Congestion of nasal mucosa without infection or allergy. (05 Mar 2000) |
| vasomotor spasm | Spasmodic contraction of the smaller arteries. (05 Mar 2000) |
| vasomotor system | The neural systems which act on vascular smooth muscle to control blood vessel diameter. The major neural control is through the sympathetic nervous system. (12 Dec 1998) |
| rhinitis, vasomotor | A form of rhinitis brought about by changes in vascular tone and permeability. The aetiology is obscure. (12 Dec 1998) |
| active centre | The part of a macromolecule at which a substrate or ligand, upon binding, produces biological activity; for an enzyme, this is the catalytic centre, the site on an enzyme that catalyses the reaction. (05 Mar 2000) |
| anospinal centre | The centre in the spinal cord that controls the contraction of the anal sphincter. (05 Mar 2000) |
