| corpus aorticum | Small masses of chromaffin cells found near the sympathetic ganglia along the abdominal aorta. They serve as chemoreceptors responsive to oxygen, carbon dioxide, and hydrogen ion concentration, and help to control respiration. (12 Dec 1998) |
|---|---|
| corpus arantii | A nodule at the centre of the free border of each semilunar valve at the beginning of the pulmonary artery and aorta. Synonym: nodulus valvulae semilunaris, Arantius' nodule, Bianchi's nodule, corpus arantii, Morgagni's nodule. (05 Mar 2000) |
| corpus atreticum | A follicle that degenerates before coming to maturity; great numbers of such atretic follicle's occur in the ovary before puberty; in the sexually mature woman, several are formed each month. Synonym: corpus atreticum. (05 Mar 2000) |
| corpus callosum | <anatomy> A great commissure (connection) between the two cerebral hemispheres (right and left). (13 Nov 1997) |
| corpus candicans | A retrogressed corpus luteum characterised by increasing cicatrization and shrinkage of the cicatricial core with an amorphous, convoluted, completely hyalinised lutein zone surrounding the central plug of scar tissue. Synonym: albicans, atretic corpus luteum, corpus candicans. Corpora allata, a pair of juvenile hormone-producing endocrine glands located near the brain in insects; action of the juvenile hormone is interrelated with that of brain hormone and ecdysone; a high concentration of the hormone at the time of molting will cause production of an additional larval instar; removal at an early larval stage causes precocious pupation, resulting in the formation of a midget adult; implantation at late larval stages can cause development of an oversized adult. (05 Mar 2000) |
| corpus ciliare | <anatomy> Tissue that includes the group of muscles that act on the eye lens to produce accommodation and the arterial circle of the iris. The inner ciliary epithelium is continuous with the pigmented retinal epithelium, the outer ciliary epithelium secretes the aqueous humour. (18 Nov 1997) |
| corpus claviculae | The sinuous portion of the clavicle between the sternal and acromial extremities. Synonym: corpus claviculae. (05 Mar 2000) |
| corpus clitoridis | The shaft or pendulous portion of the clitoris, composed of two fused corpora cavernosa clitoridae, the distal end of which is the glans clitoris. Synonym: corpus clitoridis. (05 Mar 2000) |
| corpus coccygeum | 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) |
| corpus costae | The shaft of a rib; the portion which extends laterally, anteriorly, and then medially from the tubercle. Synonym: corpus costae. (05 Mar 2000) |
| corpus dentatum | The most lateral and largest of the cerebellar nuclei; it receives the axons of the Purkinje cells of the neocerebellum (lateral areas of cerebellar cortex); together with the more medially located globosus and emboliform nuclei it is the major source of fibres composing the massive superior cerebellar peduncle or brachium conjunctivum. Synonym: nucleus dentatus cerebelli, corpus dentatum, dentatum. (05 Mar 2000) |
| corpus epididymidis | The middle part that extends downward from the head to the tail of the epididymis on the posterior surface of the testis. Synonym: corpus epididymidis. (05 Mar 2000) |
| corpus epididymis | Body of epididymis. (05 Mar 2000) |
| corpus femoris | The cylindrical shaft of the thigh bone. Synonym: corpus ossis femoris, body of thigh bone, corpus femoris. (05 Mar 2000) |
| corpus fibrosum | The small fibrous cicatricial mass in the ovary formed following the atresia of an ovarian follicle; similar to a corpus albicans but smaller. (05 Mar 2000) |
