| body righting reflexes | Reflex effects upon the neck muscles which bring the head into the correct position in space caused by stimulation of pressoreceptors in the body wall by contact with the ground. (05 Mar 2000) |

| body schema | A term for the concept which each individual has of his own body as an object in and bound by space, independently and apart from all other objects. (12 Dec 1998) |
| body surface potential mapping | Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in wolff-parkinson-white syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel. (12 Dec 1998) |
| body temperature changes | Any deviation from normal body temperature of the human body, about 98.6 degrees f. Or 37 degrees c. When taken orally. (12 Dec 1998) |
| body-weight ratio | Body weight (in grams) divided by stature (in centimeters). (05 Mar 2000) |
| body weights and measures | The systems of measurement applied to the height, weight, length, area, etc., of the human and animal body or its parts. (12 Dec 1998) |
| brassy body | A dark-coloured, usually shrunken erythrocyte in which there is a malarial parasite. (05 Mar 2000) |
| pampiniform body | <anatomy> See Parovarium. Origin: NL, from Gr. Upon + egg + to bear. Source: Websters Dictionary (01 Mar 1998) |
| mamillary body | A small, round, paired cell group that protrudes into the interpeduncular fossa from the inferior aspect of the hypothalamus. It receives hippocampal fibres through the fornix and projects fibres to the anterior thalamic nuclei and into the brainstem tegmentum. Synonym: corpus mamillare, mamillary tubercle of hypothalamus. (05 Mar 2000) |
| parabasal body | A term formerly equivalent to the DNA kinetoplast, part of the giant mitochondrion of certain parasitic flagellates. The parabasal body plus the basal body were previously thought to comprise a kinetoplast, or locomotory apparatus, but kinetoplast is now restricted to part of the DNA giant mitochondrion and parabasal body is a distinct structure near the nucleus, probably equivalent to the metazoan Golgi apparatus. (05 Mar 2000) |
| R body | <biology, microbiology> A protein structure, visible by optical microscopy, found in various bacteria, probably related to plasmid presence. Found both in free living pseudomonads and in various bacteria endosymbiotic in Paramecium. Has toxic activity against Paramecium and confers killer characteristics on Paramecium that ingest bacteria containing the structure. (18 Nov 1997) |
| paramural body | <plant biology> Membranous structure located between the plasma membrane and cell wall of plant cells. If it contains internal membranes, it may be called a lomasome, if not, it may be termed a plasmalemmasome. (18 Nov 1997) |
| ventral nucleus of trapezoid body | A cell group embedded among the fibres of the trapezoid body, the major decussation of the central auditory pathway, in the lower pons. The nucleus receives fibres from the contralateral cochlear nuclei and contributes fibres to the ascending auditory system or lateral lemniscus. Synonym: nucleus ventralis corporis trapezoidei. (05 Mar 2000) |
| paranephric body | A mass of fat lying behind the renal fascia. (05 Mar 2000) |
| paranuclear body | A set of radiating microtubules extending outward from the cytocentrum and centrosphere of a dividing cell. Synonym: aster, attraction sphere, Lavdovsky's nucleoid, paranuclear body. Origin: G. Astron, star, + sphaira, ball (05 Mar 2000) |
