| aortic bodies | Small clusters of chemoreceptive and supporting cells located near the aortic arch, the pulmonary arteries, and the coronary arteries. The aortic bodies sense pH, carbon dioxide, and oxygen concentrations in the blood and participate in the control of respiration. (12 Dec 1998) |
| Arnold's bodies | Small portions or minute fragments of erythrocytes (sometimes mistaken for blood platelets), or small "ghosts" of erythrocytes. (05 Mar 2000) |
| asbestos bodies | Ferruginous body's with asbestos fibres as a core; a histologic hallmark of exposure to asbestos. (05 Mar 2000) |
| Aschoff bodies | <pathology> Small granulomas composed of macrophages, lymphocytes and multinucleate cells grouped around eosinophilic hyaline material derived from collagen. Characteristic of the myocarditis of rheumatic fever. (18 Nov 1997) |
| Auer bodies | Rod-shaped structures of uncertain nature in the cytoplasm of immature myeloid cells, especially myeloblasts, in acute myelocytic leukaemia; may be an abnormal form of lysosomes; they contain peroxidase and acid phosphatase, and stain red by azure-eosin stains. Synonym: Auer rods. (05 Mar 2000) |
| Babes-Ernst bodies | Intracellular granules, present in many species of bacteria, which possess a strong affinity for nuclear stains. (05 Mar 2000) |
| bigeminal bodies | A bilateral single swelling of the roofplate of the embryonic midbrain that later in development becomes subdivided into a superior and an inferior colliculus. See: quadrigeminal bodies. Synonym: corpora bigemina. (05 Mar 2000) |
| Bollinger bodies | Relatively large, spheroid or ovoid, usually somewhat granular, acidophilic, intracytoplasmic inclusion body's observed in the infected tissues of birds with fowlpox; when body's are ruptured large numbers of fowlpox virus particles are released. (05 Mar 2000) |
| Borrel bodies | Particles of fowlpox virus; aggregates of Borrel body's in infected cells result in the formation of Bollinger body's. (05 Mar 2000) |
| Cabot's ring bodies | Ring-shaped or figure-of-eight structures that stain red with Wright's stain, found in red blood cells in severe anaemias, possibly a remnant of the nuclear membrane; a form of basophilic degenerative process. (05 Mar 2000) |
| Call-Exner bodies | Small fluid-filled spaces between granulosal cells in ovarian follicles and in ovarian tumours of granulosal origin; they may form a rosette-like structure. (05 Mar 2000) |
| cancer bodies | Discrete, acidophilic or amphophilic, hyaline body's of various shapes and sizes, occurring in the cytoplasm of some of the neoplastic cells and also extracellularly in the stroma of various carcinomas and sarcomas; formerly regarded by some observers as parasitic causal agents, but now thought to be products of cell necrosis (apoptosis). (05 Mar 2000) |
| vaccine bodies | Old term pertaining to intracellular body's that were erroneously thought to be forms in the life cycle of a protozoan organism, Cytorrhyctes vaccinae, postulated to be the causal agent of vaccinia. (05 Mar 2000) |
| pacchionian bodies | Tufted prolongations of pia-arachnoid, composed of numerous arachnoid villi that penetrate dural venous sinuses and effect transfer of cerebrospinal fluid to the venous system. at advanced age these are more numerous and tend to calcify. Synonym: granulationes arachnoideales, arachnoidal granulations, pacchionian bodies, pacchionian corpuscles, pacchionian glands, pacchionian granulations. (05 Mar 2000) |
