| coccygeal body | An arteriovenous (arteriolovenular) anastomosis supplied by the middle sacral artery and located on the pelvic surface of the coccyx. It was formerly called a gland (of Luschka) or a glomus and included with the paraganglia. Synonym: corpus coccygeum, arteriococcygeal gland, coccygeal gland, glomus coccygeum. (05 Mar 2000) |
| molluscum body | A disticntive intracellular spherical body in the lesions of molluscum contagiosum caused by a member of the family Poxviridae; it consists of degenerated cytoplasm and the virus. Synonym: molluscum corpuscle. (05 Mar 2000) |
| pigmented layer of ciliary body | The continuation of the pigment layer of the retina onto the posterior aspect of the ciliary body. Synonym: pigmented layer of ciliary body. (05 Mar 2000) |
| pineal body | A small conical midline body attached to the posterior part of the third ventricle and lying between the superior colliculi, below the splenium of the corpus callosum. (12 Dec 1998) |
| Weibel Palade body | <haematology> Cytoplasmic organelle found in the vascular endothelial cells of some animals, though not in the endothelium of all vessels. Although markers for endothelium, their absence does not necessarily mean the cells are not of endothelial origin. (18 Nov 1997) |

| multilamellar body | <cell biology> A specialised region of various protozoans in which phagocytosis is likely to occur. Often there is a clear concentration of microtubules or/and microfilaments in the region of the cytostome. In ciliates there may be a specialised arrangement of cilia around the cytostome.
