| body of tibia | The triangular body of tibia between its expanded proximal and distal ends. Synonym: corpus tibiae, body of tibia. (05 Mar 2000) |

| body of vertebra | The main portion of a vertebra anterior to the vertebral canal, as distinct from the arches. Synonym: corpus vertebrae. (05 Mar 2000) |
| body patterning | The morphological expression of genetic control of body shape. Clusters of homeotic genes control the morphology of animal body plans and body parts. Different body patterns may evolve through changes in gene number, regulation, or function. Recent evidence suggests that homeotic gene clusters were duplicated early in vertebrate evolution, but that arthropod and tetrapod diversity has largely involved regulatory changes in expression.

| body regions | Anatomical areas of the body. (12 Dec 1998) |
| 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) |
