| 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) |
| 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 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) |
