| systematic name | As applied to chemical substances, a systematic name is composed of specially coined or selected words or syllables, each of which has a precisely defined chemical structural meaning, so that the structure may be derived from the name. Water (trivial name) is hydrogen oxide (systematic). The systematic name of histamine (a semisystematic name) is imidazolethylamine, which indicates that a radical of imidazole replaces one hydrogen atom of ethylamine, which in turn is an ethyl group attached to an amine group. Dimethyl sulfoxide states that two methyl radicals are attached to a sulfur atom that holds an oxygen atom. Carbolic acid (trivial name) or phenol (semisystematic name) are, systematically, phenyl hydroxide or hydroxybenzene. See: semisystematic name. (05 Mar 2000) |

| systematic | 1. <biology> Pertaining or according to a system. 2. <study> Systematics is the science of naming and classifying organisms in regard to their natural relationships, deals with populations, species and higher taxa. See: taxonomy. Origin: Gr. Systematikos (09 Jan 1998) |

| systematic anatomy | A description of, especially a treatise describing, physical structure, more particularly that of man. Synonym: systematic anatomy. (05 Mar 2000) |
| systematic desensitization | A type of behaviour therapy for eliminating phobias or anxieties: the patient and therapist construct a list of imagined scenes eliciting the phobia, ranked from least to most anxiety-producing; the patient then is trained in deep muscle relaxation, and is repeatedly asked to imagine himself in the presence of the least anxiety-producing scene on the list until he feels fully relaxed while doing so; the procedure is repeated for each scene on the list until the patient develops the capacity to feel relaxed with any of the anxiety-producing scenes; real life scenes are then substituted for the imagined scenes. Synonym: reciprocal inhibition. (05 Mar 2000) |
| generic name | 1. In chemistry, a noun that indicates the class or type of a single compound; e.g., salt, saccharide (sugar), hexose, alcohol, aldehyde, lactone, acid, amine, alkane, steroid, vitamin. "Class" is more appropriate and more often used than is "generic." 2. In the pharmaceutical and commercial fields, a misnomer for nonproprietary name. 3. In the biologic sciences, the first part of the scientific name (Latin binary combination or binomial) of an organism; written with an initial capital letter and in italics. In bacteriology, the species name consists of two parts (comprising one name): the generic name and the specific epithet; in other biologic disciplines, the species name is regarded as being composed of two names: the generic name and the specific name.

| vernacular name | <zoology> The colloquial names of taxa i.e. In any language or form other than that of zoological nomenclature. Have no status in nomenclature. (09 Jan 1998) |
| collective-group name | 1. A name established expressly for a collective group. 2. A name established for a nominal genus or subgenus and later used for a collective group. (09 Jan 1998) |
| compound name | <zoology> One that is formed by the union of two or more basic components, excluding prefixes and suffixes. For example striatoradiatus, novaeguineae, fritzmuelleri, c-album (09 Jan 1998) |
| proprietary name | <pharmacology> The protected brand name or trademark, registered with the U.S. Patent Office, under which a manufacturer markets its product. It is written with a capital initial letter and is often further distinguished by a superscript R in a circle. Compare: generic name, nonproprietary name. Origin: L. Proprietas, ownership (05 Mar 2000) |
| semisystematic name | A name of a chemical of which at least one part is systematic and at least one part is not (i.e., is trivial). For example, calciferol includes the -ol suffix denoting an -OH radical, while calcifer-, which has no systematic meaning, is used only in this word. Cortisone contains the -one suffix, indicating a ketone group, but the rest of the term derives from cortex (adrenal). Hippuric acid (trivial) may be defined as N-benzoylglycine (semitrivial name); benzoyl is systematic for the C6H5-CO-radical, whereas glycine is the trivial name for alpha-aminoacetic (or 2-aminoethanoic, to be completely systematic) acid, and the N signifies that the benzoyl is attached to the nitrogen of glycine; from this, the structure C6H5-CO-NH-CH2-COOH is uniquely defined. Many generic or nonproprietary names of drugs, including USAN names, hormones, etc., are semitrivial in this chemical sense, although often termed trivial names; distinction between trivial and semitrivial is not often made. Synonym: semitrivial name. (05 Mar 2000) |

| hybrid name | <zoology> Names given to hybrids are not normally available, as they are individuals, not populations, and hence not taxa. (09 Jan 1998) |
| NAME | Acronym for nevi, atrial myxoma, myxoid neurofibromas, and ephilides. See: NAME syndrome. (05 Mar 2000) |
| name bearing type | <zoology> The type genus, type species, holotype, lectotype, series of syntypes, neotype, type slide, or hapantotype, that provides the objective standard of reference whereby the application of the name of a taxon can be determined. (09 Jan 1998) |
| NAME syndrome | <syndrome> The concurrence of nevi, atrial myxoma, myxoid neurofibromas, and ephilides. (05 Mar 2000) |
| nonproprietary name | A short name (often called a generic name) of a chemical, drug, or other substance that is not subject to trademark (proprietary) rights but is, in contrast to a trivial name, recognised or recommended by government agencies (e.g., Federal Food and Drug Administration) and by quasi-official organizations (e.g., U.S. Adopted Names Council) for general public use. Like a proprietary name, it is almost always a coined designation derived without using set criteria. Compare: trivial name, proprietary name, semisystematic name, systematic name. (05 Mar 2000) |
