| division | 1. The act of dividing. 2. <zoology> A rank that if treated as a division of a genus or subgenus is deemed to be of subgeneric rank for the purposes of nomenclature. 3. A taxon at the rank of division. The second highest taxonomic classification for the kingdoms Plantae (plants) and Fungi, between kingdom level and class level. (09 Jan 1998) |

| division septum | <cell biology> The cell wall that forms between daughter cells at the end of mitosis in plant cells or just before separation in bacteria. (18 Nov 1997) |
| indirect nuclear division | <cell biology> A method of indirect division of a cell, consisting of a complex of various processes, by means of which the two daughter nuclei normally receive identical complements of the number of chromosomes characteristic of the somatic cells of the species. Mitosis, the process by which the body grows and replaces cells, is divided into four phases. 1. Prophase: formation of paired chromosomes, disappearance of nuclear membrane, appearance of the achromatic spindle, formation of polar bodies. 2. Metaphase: arrangement of chromosomes in the equatorial plane of the central spindle to form the monaster. Chromosomes separate into exactly similar halves. 3. Anaphase: the two groups of daughter chromosomes separate and move along the fibres of the central spindle, each toward one of the asters, forming the diaster. 4. Telophase: the daughter chromosomes resolve themselves into a reticulum and the daughter nuclei are formed, the cytoplasm divides, forming two complete daughter cells. NOTE: the term mitosis is used interchangeably with cell division, but strictly speaking it refers to nuclear division, whereas cytokinesis refers to division of the cytoplasm. In some cells, as in many fungi and the fertilized eggs of many insects, nuclear division occurs within the cell unaccompanied by division of the cytoplasm and formation of daughter cells.

| equatorial division | Nuclear division in which each chromosome divides equally. (05 Mar 2000) |
| first meiotic division | The first of two consecutive divisions of the nucleus of an eukaryotic cell during the process of meiosis. It includes the following stages of meiosis: prophase I, metaphase I, anaphase I, and telophase I. (09 Oct 1997) |
| cancer, gastric | Cancer of the stomach, the major organ that holds food for digestion. Stomach cancer (gastric cancer) can develop in any part of the stomach and spread to other organs. Stomach ulcers do not appear to increase a person's risk of developing stomach cancer. Symptoms of stomach cancer are often vague, such as loss of appetite and weight. The cancer is diagnosed with a biopsy of stomach tissue during a procedure called an endoscopy. (12 Dec 1998) |
| vagotomy, proximal gastric | Vagal denervation of that part of the stomach lined with acid secreting mucosa. Since the procedure leaves the vagal branches to the antrum and pylorus intact, it circumvents gastric drainage required with truncal vagotomy techniques. (12 Dec 1998) |
| gastric | <anatomy> Of or relating to the stomach. (09 Oct 1997) |
| gastric acid | Hydrochloric acid present in gastric juice. (12 Dec 1998) |
| gastric acidity determination | Gastric analysis for determination of free acid or total acid. (12 Dec 1998) |
| gastric algid malaria | See: algid malaria. Induced malaria, malaria acquired by artificial means, e.g., via blood transfusion, common syringes, or malariotherapy. Intermittent malaria, a malarial fever, usually of the tertian or quartan type, in which there is complete apyrexia, with absence of the other symptoms, in the intervals between the paroxysms. (05 Mar 2000) |
| gastric analysis | Measurement of pH and acid output of stomach contents; basal acid output can be determined by collecting the overnight gastric secretion or by a 1-hr collection; maximal acid output is determined following injection of histamine; output is measured by titration with a strong base. (05 Mar 2000) |
| gastric area | One of a number of small polygonal area's, 1-6 mm in diameter, separated by linear depressions on the surface of the mucous membrane of the stomach; they contain the gastric pits, with several gastric glands opening into each pit. Synonym: area gastrica. (05 Mar 2000) |
| gastric arteries | Arteries supplying the stomach along the lesser curvature. See: left gastric artery, right gastric artery. (05 Mar 2000) |
| gastric atrophy | <gastroenterology> A condition in which the stomach muscles shrink and become weak. It results in a lack of digestive juices. Gastritis: Inflammation of the stomach. (12 Dec 1998) |
