| demilune body | A circular body of extreme transparency except for a crescentic punctate substance on one edge which contains haemoglobin. The body is much larger than a red blood cell, but is thought possibly to be a degenerated red blood cell swollen by imbibition; it has been found in malaria and in convalescence from typhoid fever; the transparent portion is called the glass body.

| Symington's anococcygeal body | <anatomy> A musculofibrous band that passes between the anus and the coccyx. Synonym: ligamentum anococcygeum, anococcygeal body, raphe anococcygea, Symington's anococcygeal body. (05 Mar 2000) |
| dorsal nucleus of trapezoid body | A circumscript, bipartite cell group located ventrolaterally in the lower pontine tegmentum, immediately dorsal to the trapezoid body; the nucleus receives fibres from both the ipsilateral and contralateral cochlear nuclei, and contributes fibres to the lateral (auditory) lemniscus of both sides. It is believed to be prominently involved in the function of spatial localization of sound. Synonym: nucleus dorsalis corporis trapezoidei, oliva superior, superior olivary nucleus, superior olive.

| inclusion body disease | <disease> An illness in newborns caused by viral infection, symptoms includefever, cellular enlargement, microscopically-visible clumps of viralparticles or proteins in the cytoplasm and nuclei of affected cells, enlargementof the spleen and liver. Long-term effects of the disease may includemental retardation. (09 Oct 1997) |
| inclusion body encephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
| inclusion body myositis | <radiology> Common form of inflamatory myopathy, most common in the elderly, equal sex incidence, sporadic idiopathic disease (very rarely familial), misdiagnosed as steroid-resistant polymyositis symptoms, presents as a painless slowly progressive proximal myopathy, may cause dysphagia, mild to moderate muscle wasting diagnosis, serum creatine kinase levels usually normal or only slightly elevated, EMG may show non-specific myopathic features, diagnosis on muscle biopsy, inclusion bodies seen in rimmed vacuoles in skeletal muscle fibres treatment, steroids and immunosuppression generally ineffective, rare patients reported who have made a response to treatment pathogenesis, unknown, ubiquitin, prion protein, tau protein found in inclusions, abnormal mitchondria seen in some case (12 Dec 1998) |
| inclusion body rhinitis | A respiratory disease of pigs caused by the cytomegalovirus porcine herpesvirus 2 and characterised by rhinitis and conjunctivitis in young pigs. (05 Mar 2000) |
| infrapatellar fat body | The fatty mass that occupies the area between the patellar ligament and the infrapatellar synovial fold of the knee joint. Synonym: corpus adiposum infrapatellare, infrapatellar fat body. (05 Mar 2000) |
| intercarotid body | A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control. (12 Dec 1998) |
| intermediate body of Flemming | <cell biology> Dense structure formed during cytokinesis at the cleavage furrow. It consists of remnants of spindle fibres and other amorphous material and disappears before cell division is completed. (18 Nov 1997) |
| ivory vertebral body | <radiology> Single or multiple very dense vertebra: collapse, metastases, sclerotic metastasis or treated lytic metastasis, preservation of disc space and vertebral body size, Paget's disease, usually single vertebral body, expanded body with thickened cortex and coarsened trabeculation, disc space preserved, lymphoma, preservation of disc space and vertebral body size, infection (low grade), end plate destruction, disc space narrowing, paraspinal soft tissue mass (12 Dec 1998) |
| Odland body | A membrane-bound granule, 100 to 500 nm in diameter, located in the upper layers of the stratum spinosum of certain stratified squamous epithelia. Synonym: lamellar granule, membrane-coating granule, Odland body. (05 Mar 2000) |
| olivary body | <zoology> A genus of polished marine gastropod shells, chiefly tropical, and often beautifully coloured. Origin: L. An olive. Source: Websters Dictionary (01 Mar 1998) |
| three-body collisions | <radiobiology> It is possible (but generally rare) to have three particles collide simultaneously, instead of just two. (09 Oct 1997) |
| 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) |
