| 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) |
| sympathetic trunk | One of the two long ganglionated nerve strands alongside the vertebral column that extend from the base of the skull to the coccyx; they are connected to each spinal nerve by gray rami and receive fibres from the spinal cord through white rami connecting with the thoracic and upper lumbar spinal nerves. Synonym: truncus sympathicus, gangliated cord. (05 Mar 2000) |
| sympathetic uveitis | A bilateral inflammation of the uveal tract caused by a perforating wound of one eye that injures the uvea. (05 Mar 2000) |
| sympathetoblast | A primitive cell derived from the neural crest glia; with the pheochromoblasts, sympathoblast's enter into the formation of the adrenal medulla and sympathetic ganglia. Synonym: sympathetoblast, sympathicoblast. Origin: sympatho-+ G. Blastos, germ (05 Mar 2000) |
