| chemoreceptor | A receptor adapted for excitation by chemical substances, for example, olfactory and gustatory receptors or a sense organ, as the carotid body or the aortic (supracardial) bodies, which is sensitive to chemical changes in the blood stream, especially reduced oxygen content and reflexly increases both respiration and blood pressure. See: receptor. (18 Nov 1997) |

| chemoreceptor tumour | Aortic body, carotid body, chemoreceptor, or glomus jugulare tumour; nonchromaffin paraganglioma; receptoma; a relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body, glomus jugulare, and aortic bodies; consisting histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. Compare: paraganglioma. Synonym: aortic body tumour, carotid body tumour, chemoreceptor tumour, glomus jugulare tumour, nonchromaffin paraganglioma. Origin: chemo-+ G. Dektes, receiver, fr. Dechomai, to receive, + -oma, tumour (05 Mar 2000) |
| chemoreceptors | Cells specialised to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptors may monitor external stimuli, as in taste and olfaction, or internal stimuli, such as the concentrations of oxygen and carbon dioxide in the blood. (12 Dec 1998) |
| medullary chemoreceptor | The chemoreceptor's in or near the ventrolateral surface of the medulla that are stimulated by local acidity. (05 Mar 2000) |
|---|---|
| peripheral chemoreceptor | The chemoreceptor's in the carotid and aortic bodies that are stimulated by chemical changes in the composition of the blood such as hypoxia. (05 Mar 2000) |
Synonyms : Chemoreceptor

| chemoreceptor s. |
the system of body structures, principally the carotid body, the aortic bodies, and the glomus jugulare, that respond to variations in oxygen tension and carbon dioxide tension of the blood and may play a role in the regulation of respiration.

| chemoreceptor trigger z. |
part of the area postrema in the fourth ventricle that mediates physiological reactions to various chemicals and drugs and plays an indirect role in stimulation of vomiting. It mediates some impulses that in turn stimulate the vomiting center in the medulla.
