| sympathoadrenal | Relating to the sympathetic part of the autonomic nervous system and the medulla of the adrenal gland, as the postganglionic neurons. (05 Mar 2000) |
| sympathoblast | 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) |
| sympathoblastoma | <tumour> Obsolete term for neuroblastoma. Origin: sympathoblast + G. -oma, tumour (05 Mar 2000) |
| sympathochromaffin cell | The cell type in the embryonic suprarenal gland from which both sympathetic ganglion cell's and chromaffin cell's are developed. (05 Mar 2000) |
| sympathogonia | The completely undifferentiated cells of the sympathetic nervous system. Origin: sympatho-+ G. Gone, seed (05 Mar 2000) |
| sympathogonioma | <tumour> Obsolete term for neuroblastoma. Origin: sympathogonia + G. -oma, tumour (05 Mar 2000) |
| sympatholytic | Denoting antagonism to or inhibition of adrenergic nerve activity. See: adrenergic blocking agent, antiadrenergic. Synonym: sympathicolytic. Origin: sympatho-+ G. Lysis, a loosening (05 Mar 2000) |
| sympatholytics | Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the adrenergic antagonists and drugs that deplete norepinephrine or reduce the release of transmitters from adrenergic postganglionic terminals (see adrenergic agents). Drugs that act in the central nervous system to reduce sympathetic activity (e.g., centrally acting alpha-2 adrenergic agonists, see adrenergic alpha-agonists) are included here. (12 Dec 1998) |
| sympathomimetic | 1. <physiology> The mimicking the effects of impulses conveyed by adrenergic postganglionic fibres of the sympathetic nervous system. 2. <pharmacology> An agent that produces effects similar to those of impulses conveyed by adrenergic postganglionic fibres of the sympathetic nervous system. Usually refers to drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Includes drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters. Synonym: adrenergic. Origin: Gr. Mimetikos = imitative (12 Dec 1998) |
| sympathomimetic 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) |
| sympathomimetic amines | A broad class of chemicals which mimic the actions of activation of the sympathetic nervous system and have an amine (usually beta-phenyl-ethylamine) basic structure; examples include isoproterenol, amphetamine, ephedrine, and phenylephrine. (05 Mar 2000) |

| sympathomimetic |
Sympathomimetics are a class of drugs whose properties mimic those of a stimulated sympathetic nervous system. As such they increase cardiac output, dilate bronchioles, and usually produce constriction of blood vessels. Sympathomimetics include the naturally occurring substances adrenaline (epinephrine), noradrenaline (norepinephrine), and other catecholamines such as dopamine, as well as the synthetic drugs pseudoephedrine, phenylephrine, and phenylpropanolamine. ...

| sympathoadrenal |
The sympathoadrenal lineage is one fate of neural crest cells and represents a common progenitor of the adrenergic sympathetic neurons and the medullary cells of the adrenal gland.

| sympathomimetic |
Producing effects similar to the 'flight or fight' response, which means the body is alerted to a danger of some sort and prepares to basically run or fight. Sympathomimetic effects include increased heart rate, sweating, and increased blood pressure.
