| 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.

| chemical formula |
A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. It identifies each type of element by its chemical symbol and identifies the number of atoms of such element to be found in each discrete molecule of that compound. The number of atoms (if greater than one) is indicated as a subscript. For non-molecular substances the subscripts indicate the ratio of elements in the empirical formula. ...

| chemotaxis |
Chemotaxis is the phenomenon in which bodily cells, bacteria, and other single-celled or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by swimming towards the highest concentration of food molecules, or to flee from poisons (for example, phenol). In multicellular organisms, chemotaxis is critical in development as well as normal function. ...

Chemical fertilizers are manufactured chemicals designed to give a boost to plant growth and supply nutrients that are lacking. Usually the most important of these are nitrogen. Nitrogen (N) is important for leaf growth. Phosphorous (P) is needed for root health. Potash (K) is used in flower development. These are the primary chemicals in "complete" fertilizers. Often, small amounts of other chemicals such as sulfur, iron, magnesium, also are included.
