| whole-body counter | Shielding and instrumentation, usually involving more than one detector, designed to evaluate the total-body burden of various gamma-emitting nuclides. (05 Mar 2000) |
|---|---|
| whole-body counting | Measurement of radioactivity in the entire human body. (12 Dec 1998) |
| whole-body irradiation | Irradiation of the whole body with ionizing or non-ionizing radiation. It is applicable to humans or animals but not to microorganisms. (12 Dec 1998) |
| whole-body titration curve | A graphic representation of the in vivo changes in hydrogen ion, PaCO2, and bicarbonate which occur in arterial blood in response to primary acid-base disturbances. (05 Mar 2000) |
| wolffian body | <anatomy> The middle one of the three pairs of embryonic renal organs developed in most vertebrates; the Wolffian body. Origin: NL, fr. Gr. Middle + kidney. Source: Websters Dictionary (01 Mar 1998) |
| plethysmography, whole body | Measurement of the volume of gas in the lungs, including that which is trapped in poorly communicating air spaces. It is of particular use in chronic obstructive pulmonary disease and emphysema. (12 Dec 1998) |
| multilamellar body | <cell biology> A specialised region of various protozoans in which phagocytosis is likely to occur. Often there is a clear concentration of microtubules or/and microfilaments in the region of the cytostome. In ciliates there may be a specialised arrangement of cilia around the cytostome. (18 Nov 1997) |
| multivesicular body | Secondary lysosome containing many vesicles of around 50 nm diameter. (18 Nov 1997) |
| polar body | <cell biology> In animals each meiotic division of the oocyte leads to the formation of one large cell (the egg) and a small polar body as the other cell. Polar body formation is a consequence of the very eccentric position of the nucleus and the spindle. (18 Nov 1997) |
| polyhedral body | An inclusion body associated with replication of certain insect viruses. (05 Mar 2000) |
| myelin body | <cell biology> Structure that can form spontaneously when bilayer forming phospholipids (e.g. Egg lecithin) are added to water. They are reminiscent of the concentric layer structure of myelin. (18 Nov 1997) |
| Councilman body | An eosinophilic globule, seen in the liver in yellow fever, derived from necrosis of a single hepatic cell. Synonym: Councilman's lesion. (05 Mar 2000) |
| myositis, inclusion body | A progressive inflammatory myopathy primarily involving muscles of the pelvic region and legs, usually seen in older people. The muscles are infiltrated by mononuclear inflammatory cells, sarcoplasmic vacuoles, masses of filaments and filamentous microtubules, and sometimes eosinophilic bodies. (12 Dec 1998) |
| pontobulbar body | A collection of nerve cells in the lower part of the medulla oblongata forming a ridge which crosses the restiform body obliquely. Synonym: corpus pontobulbare. (05 Mar 2000) |
| posterior quadrigeminal body | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
