| sympath | sympathetic |
| sympathetic hormone | <protein> A neurohormone, such asepinephrine, produced in response to stimulationof the sympathetic nervous system and which acts as a chemical mediator invarious organs. (09 Oct 1997) |
|---|---|
| sympathetic hypertonia | Overfunction of the sympathetic nervous system, often experienced as anxiety. (05 Mar 2000) |
| sympathetic imbalance | Hyperexcitability of the vagus nerve, a condition in which the vagus nerve dominates in the general functioning of the body organs. It is marked by vasomotor instability, constipation, sweating and involuntary motor spasms with pain. (18 Nov 1997) |
| sympathetic iridoplegia | Iridoplegia due to the paralysis of the sympathetically innervated dilator pupillae muscle. (05 Mar 2000) |
| sympathetic iritis | Iritis consecutive to a similar condition in the other eye. (05 Mar 2000) |
| sympathetic nerve | <anatomy, nerve> One of the nerve's of the sympathetic nervous system. (05 Mar 2000) |
| sympathetic nervous system | <anatomy, physiology> One of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. most sympathetic neurons, but not all, use noradrenaline as a post ganglionic neurotransmitter. (19 Jan 1998) |
| sympathetic ophthalmia | A serous or plastic uveitis caused by a perforating wound of the uvea followed by a similar severe reaction in the other eye that may lead to bilateral blindness. Synonym: transferred ophthalmia. (05 Mar 2000) |
| sympathetic part | <anatomy, physiology> One of the two divisions of the vertebrate autonomic nervous system (the other being the parasympathetic nervous system). The sympathetic preganglionic neurons have their cell bodies in the thoracic and lumbar regions of the spinal cord and connect to the paravertebral chain of sympathetic ganglia. Innervate heart and blood vessels, sweat glands, viscera and the adrenal medulla. most sympathetic neurons, but not all, use noradrenaline as a post ganglionic neurotransmitter. (19 Jan 1998) |
| sympathetic plexuses | Autonomic plexuses, in which postsynaptic sympathetic nerve fibres are predominant. (05 Mar 2000) |
| sympathetic reflex 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) |
| sympathetic root of ciliary ganglion | Postganglionic fibres,having cell bodies in the superior cervical ganglion, branching from the carotid plexus passing through the ciliary ganglion without synapse to reach the eyeball. Synonym: radix sympathica ganglii ciliaris. (05 Mar 2000) |
| sympathetic saliva | Submaxillary saliva obtained by stimulation of the sympathetic fibres innervating the gland. (05 Mar 2000) |
| sympathetic segment | A divison of the sympathetic trunks based on the origins of the gray communicating branches. (05 Mar 2000) |
| sympathetic symptom | A disturbance of sensation or function in an organ or part more or less remote from the morbid condition giving rise to it; e.g., muscle spasm due to joint inflammation. Synonym: sympathetic symptom. (05 Mar 2000) |
