| threshold body | Any material (e.g., glucose) that is excreted in the urine only when its plasma concentration exceeds a certain value, termed its threshold. Synonym: threshold body. (05 Mar 2000) |
| thyroid body | A butterfly-shaped endocrine gland in the neck that is found on both sides of the trachea windpipe). It secretes the hormone thyroxine which controls the rate of metabolism. (27 Sep 1997) |
| Ehrlich's inner body | A round oxyphil body found in the red blood cell in case of haemocytolysis due to a specific blood poison. Synonym: Heinz-Ehrlich body. (05 Mar 2000) |
| embryonal tumour of ciliary body | <tumour> An epitheliomatous tumour of the nonpigmented layer of the ciliary epithelium. Synonym: embryonal tumour of ciliary body. (05 Mar 2000) |
| total body hypothermia | The deliberate reduction of total body temperature, in order to reduce tissue metabolism. (05 Mar 2000) |
| total body irradiation | Radiotherapy often given in several doses prior to bone marrow transplantation with the aim of killing any residual leukaemia in the patient. It is used in conjunction with high-dose anti-cancer drugs. The procedure and its side-effects will be discussed individually with the patient. (13 Nov 1997) |
| total body water | The sum of intracellular water and extracellular water (volume). About 60% of body weight. (05 Mar 2000) |
| trapezoid body | A plate of transverse fibres running over the dorsal (deep) border of the pontine nuclei; it is formed by ascending auditory fibres that cross to the opposite side of the brainstem. Synonym: corpus trapezoideum, trapezoid. (05 Mar 2000) |
| epithelial body | <anatomy, endocrinology> Four small endocrine glands lying close or embedded in the posterior surface of the thyroid gland. They secrete the hormone parathormone. (27 Sep 1997) |
| tuffstone body | Membrane-bound electron-dense granules, measuring about 0.5 um in diameter, found primarily in Schwann cells of patients suffering from metachromatic leukodystrophy; the name alludes to their resemblance to volcanic limestone. (05 Mar 2000) |
| turbinated body | A concha with its covering of mucous membrane and other soft parts. Synonym: turbinal. Synonym: inferior nasal concha, middle nasal concha, superior nasal concha, supreme nasal concha. (05 Mar 2000) |
| tympanic body | One of the mucous gland's in the mucosa of the tympanic cavity. Synonym: tympanic body. (05 Mar 2000) |
| juxtaglomerular body | A collection of cells around the renal glomerular arterioles that contain cytoplasmic granules, probably composed of renin. Synonym: periarterial pad. (05 Mar 2000) |
| juxtarestiform body | A medial (smaller) subdivision of the inferior cerebellar peduncle (corpus restiforme) composed of fibres reciprocally connecting the vestibular nuclei with the cerebellum, in particular the latter's nodulus, flocculus, and uvula vermis. It also carries primary sensory fibres from the vestibular ganglia to the cerebellum, as well as cerebellar projections to the rhombencephalic reticular formation and vestibular nuclei.
