| coeliac rickets | Arrested growth, and osseous deformities associated with defective absorption of fat and calcium in coeliac disease. (05 Mar 2000) |

| coeliac sprue | <gastroenterology> An inherited disease where the intestinal lining is inflamed in response to the ingestion of a protein known as gluten. Gluten is present in many grains including rye, oats, barley and triticale. Symptoms in infants include diarrhoea, slow growth, bloody stools, weight loss, vomiting and clay-coloured stools. Symptoms in adults include abdominal distention, abdominal pain, fatigue, weight loss, bone pain and bone tenderness. Treatment involves the life-long avoidance of gluten. (10 Jan 1998) |
| coeliac syndrome | <disease, gastroenterology> Gluten enteropathy: atrophy of villi in small intestine leads to impaired absorption of nutrients. Caused by sensitivity to gluten (protein of wheat and rye). Sufferers have serum antibodies to gluten and show delayed hypersensitivity to gluten, the risk factor is ten times greater in HLA B8 positive individuals. (18 Nov 1997) |
| coeliac trunk | Origin, abdominal aorta just below diaphragm; branches, left gastric, common hepatic, splenic. Synonym: truncus coeliacus, arteria coeliaca, coeliac artery, coeliac axis, Haller's tripod. (05 Mar 2000) |
| coeliagra | Rarely used term for sudden painful affection of the stomach or other abdominal organs. Origin: G. Koilia, belly, + agra, seizure (05 Mar 2000) |
| coelom | <biology, embryology> An internal fluid-filled body cavity (other than the gut) within an organism, it lies between the gut (derived from the endoderm) and the outer body wall (derived from the ectoderm) and is lined entirely with tissue derived from the mesoderm. It is formed from the mesoderm during embryonic development. It is found in triploblastic animals called coelomates. (09 Oct 1997) |
| coelomate | <embryology> A triploblastic organism which has an internal, fluid-filled body cavity which originated from the mesoderm during embryonic development. This cavity surrounds the gut, may contain various other organs, and is called a coelom. It differs from the pseudocoels of the pseudocoelomates because it is not derived from the blastocoel. The term is used to classify multicellular animals by developmental pattern. (09 Oct 1997) |
| coelomic metaplasia | Potential of coelomic epithelium to differentiate into several different histologic cell types. (05 Mar 2000) |
| coenesthesia | The general sense of bodily existence; the sensation caused by the functioning of the internal organs. Synonym: coenesthesia, sixth sense. Origin: G. Koinos, common, + aisthesis, sensation (05 Mar 2000) |
| coeno- | Shared in common. See: ceno-. Origin: G. Koinos, common (05 Mar 2000) |
| coenobium | <plant biology> Colony of cells formed by certain green algae, in which little or no specialisation of the cells occurs. The cells are often embedded in a mucilaginous matrix. Examples: Volvox, Pandorina. (18 Nov 1997) |
| coenocyte | <biology> Organism that is not subdivided into cells but has many nuclei within a mass of cytoplasm (a syncytium), as for example some fungi and algae and the acellular slime mould Physarum. (18 Nov 1997) |
| coenocytic | Pertaining to or having characteristics of a cenocyte. Synonym: coenocytic. (05 Mar 2000) |
| coenurosis | Cenuriasis Disease produced by the presence of a cenuris cyst that, in sheep, causes a brain infection known as "gid" for the giddy gait induced in the infected animal; human cenurosis has been reported but is extremely unusual, in contrast with hydatid disease. Synonym: coenurosis. (05 Mar 2000) |
| Coenurus | Former generic name, now used to designate larval forms of taenioid cestodes in which a bladder is formed with a number of invaginated scoleces developing within; distinguished from a hydatid cyst by the absence of free-floating daughter cyst colonies budded off within the bladder; Coenurus larvae are found in members of the genus Multiceps. Origin: G. Koinos, common, + oura, tail (05 Mar 2000) |
