| pattern recognition | In information retrieval, machine-sensing or identification of visible patterns (shapes, forms, and configurations). (harrod's librarians' glossary, 7th ed) (12 Dec 1998) |
|---|---|
| pattern recognition, visual | Visually perceived characters, shapes, displays, or designs. (12 Dec 1998) |
| recognition factors | Factors which effect "recognition" of target antigens by polymorphonuclear leukocytes; apparently the Fc portion of antibody molecules and the activated third component of complement (C3), for both of which phagocytes have receptor sites. (05 Mar 2000) |
| recognition sequence | A nucleotide sequence --typically composed of 4, 6, or 8nucleotides -- that is recognised by a restriction endonuclease. Type II enzymes cut (and theircorresponding modification enzymes methylate) within or very near the recognition sequence. (09 Oct 1997) |
| recognition time | The interval between the application of a stimulus and the recognition of its nature. (05 Mar 2000) |
| cell recognition | <cell biology> Interaction between cells that is possibly dependent upon specific adhesion. Since the mechanism is not entirely clear in most cases, the term should be used with caution. (26 Mar 1998) |
| physiological | Of or pertaining to physiology; relating to the science of the functions of living organism; as, physiological botany or chemistry. Source: Websters Dictionary (01 Mar 1998) |
| physiological adaptation | A peculiarity of the basic physical and chemical activities that occur in cells and tissues of a species, which results in it being better fitted to its environment (for example, ability to absorb nutrients under low oxygen tensions). (09 Oct 1997) |
| physiological anatomy | Anatomy studied in its relation to function. Synonym: morphophysiology, physiological anatomy. (05 Mar 2000) |
| physiological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
| physiological drives | Those drives such as hunger and thirst which stem from the biological needs of an organism. Synonym: primary drives. (05 Mar 2000) |
| physiological homeostasis | bernard-Cannon homeostasis |
| physiological intracranial calcification | <radiology> Pineal gland, habenular commisure, choroid plexus, dura, pacchionian bodies, basal ganglia and dentate nucleus (12 Dec 1998) |
| physiological processes | The functions of living organisms and their parts, and the physical and chemical factors and processes involved. (12 Dec 1998) |
| physiological sphincter | A section of a tubular structure that acts as if it has a band of circular muscle to constrict it, although no such specialised structure can be found on morphological examination. Synonym: functional sphincter, radiological sphincter. (05 Mar 2000) |
