| chemoorganotroph | An organism which oxidizes chemical bonds for energy but requires organic carbon compounds to grow. A type of heterotroph. (09 Oct 1997) |
|---|---|
| chemoorganotrophic | Pertaining to a chemoorganotroph. Synonym: chemoheterotrophic. (05 Mar 2000) |
| chemopallidectomy | Destruction of the globus pallidus by injection of a chemical agent. Synonym: chemopallidotomy. Origin: chemo-+ globus pallidus + G. Ektome, excision (05 Mar 2000) |
| chemopallidothalamectomy | Destruction of portions of the globus pallidus and thalamus by injection of a chemical substance. Origin: chemo-+ globus pallidus + thalamus + G. Ektome, excision (05 Mar 2000) |
| chemopallidotomy | Synonym: chemopallidectomy. Origin: chemo-+ globus pallidus + G. Tome, incision (05 Mar 2000) |
| chemoprevention | The use of natural or laboratory-made substances to prevent cancer. (12 Dec 1998) |
| chemoprophylaxis | <epidemiology> Drug treatment designed to prevent future occurrences of disease. Treatment may be chemotherapy as far as an individual is concerned but chemopropylactic for the population as a whole. (05 Dec 1998) |
| 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) |
| chemoreflex | A reflex initiated by the stimulation of chemoreceptors, e.g., of a carotid body. (05 Mar 2000) |
| chemorepellant | Opposite of chemoattractant. (18 Nov 1997) |
| chemoresistance | Resistance of cells to the actions of specific chemicals. (09 Oct 1997) |
| chemosensitive | Capable of perceiving changes in the chemical composition of the environment, e.g., changes in the oxygen and carbon dioxide content of the blood. (05 Mar 2000) |
| chemosensitizer | Drugs or chemicals that enhance the therapeutic effects of chemotherapy drugs and therefore improve their effectiveness. (09 Oct 1997) |
