| lumbosacral trunk | A large nerve, formed by the union of the fifth lumbar and first sacral nerves, with a branch from the fourth lumbar nerve, which enters into the formation of the sacral plexus. Synonym: truncus lumbosacralis. (05 Mar 2000) |
|---|---|
| ganglia, sympathetic | Ganglia of the sympathetic nervous system including the paravertebral and the prevertebral ganglia. Among these are the sympathetic chain ganglia, the superior, middle, and inferior cervical ganglia, and the aorticorenal, coeliac, and stellate ganglia. (12 Dec 1998) |
| reflex sympathetic dystrophy | A syndrome of pain and tenderness, usually to a hand or foot, associated with vasomotor instability, skin changes and rapid development of bony demineralisation (osteoporosis). Frequently will follow a localised trauma, stroke or peripheral nerve injury. (27 Sep 1997) |
| reflex sympathetic dystrophy syndrome | <syndrome> A condition that features a group of typical symptoms, including pain (often burning type), tenderness, and swelling of an extremity associated with varying degrees of sweating, warmth and/or coolness, flushing, discoloration, and shiny skin. (12 Dec 1998) |
| nervous system, sympathetic | A part of the nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. The sympathetic nervous system together with the parasympathetic nervous system (that slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles) constitute the autonomic nervous system. (12 Dec 1998) |
| sympathetic | 1. <psychology> Pertaining to, caused by or exhibiting sympathy. 2. <physiology> A sympathetic nerve or the sympathetic nervous system. Origin: Gr. Sympathetikos (19 Jan 1998) |
| sympathetic agent | An agent that evokes responses similar to those produced by adrenergic nerve activity (e.g., epinephrine, ephedrine, isoproterenol). Synonym: adrenergic amine, adrenomimetic amine, sympathetic amine. (05 Mar 2000) |
| sympathetic amine | An agent that evokes responses similar to those produced by adrenergic nerve activity (e.g., epinephrine, ephedrine, isoproterenol). Synonym: adrenergic amine, adrenomimetic amine, sympathetic amine. (05 Mar 2000) |
| sympathetic blockade | Interruption of transmission in sympathetic ganglia or conduction of impulses in pre-or postganglionic sympathetic nerve fibres. (05 Mar 2000) |
| sympathetic branch to submandibular ganglion | Branch to the submandibular ganglion composed of postsynaptic sympathetic fibres from the internal carotid plexus conveyed largely by a periarterial plexus of the facial artery. Synonym: ramus sympathicus [sympatheticus] ad ganglion submandibulare. (05 Mar 2000) |
| sympathetic denervation | <procedure, surgery> Removal of the sympathetic nervous systems influence in one area of the body. This may be accomplished with drugs or surgery. A treatment for reflex sympathetic dystrophy. (27 Sep 1997) |
| sympathetic fibres, postganglionic | Nerve fibres which project from sympathetic ganglia to synapses on target organs. Sympathetic postganglionic fibres use norepinephrine as transmitter, except for those innervating eccrine sweat glands (and possibly some blood vessels) which use acetylcholine. They may also release peptide cotransmitters. (12 Dec 1998) |
| sympathetic formative cell | A neuroblast of the embryonic autonomic nervous system. (05 Mar 2000) |
| sympathetic ganglia | Those ganglia of the autonomic nervous system that receive efferent fibres originating from preganglionic visceral motor neurons in the intermediolateral cell column of thoracic and upper lumbar spinal segments (T1-L2). On the basis of their location, the sympathetic ganglia can be classified as paravertebral ganglia (ganglia trunci sympathici) and prevertebral ganglia (ganglia coeliaca). See: autonomic nervous system. (05 Mar 2000) |
| sympathetic heterochromia | Heterochromia iridis occurring after lesions of the cervical sympathetic nerves. (05 Mar 2000) |
