| corpus amygdaloideum | Almond-shaped group of basal nuclei anterior to the inferior horn of the lateral ventricle of the brain, within the temporal lobe. The amygdala is part of the limbic system. (12 Dec 1998) |

| corpus amylaceum | One of a number of small ovoid or rounded, sometimes laminated, bodies resembling a grain of starch and found in nervous tissue, in the prostate, and in pulmonary alveoli; of little pathological significance, and apparently derived from degenerated cells or proteinaceous secretions. Synonym: amniotic corpuscle, amylaceous corpuscle, amyloid corpuscle, colloid corpuscle. (05 Mar 2000) |
| 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 cavernosum clitoridis | One of the two parallel columns of erectile tissue forming the body of the clitoris; they diverge at the root to form the crura of the clitoris. Synonym: cavernous body of clitoris. (05 Mar 2000) |
| corpus cavernosum conchae | Erectile tissue in the mucous membrane covering the conchae of the nasal cavity. Synonym: plexus cavernosi concharum, corpus cavernosum conchae. (05 Mar 2000) |
| corpus cavernosum urethrae | The median column of erectile tissue located between and ventral to the two corpora cavernosa penis; posteriorly it expands into the bulbus penis and anteriorly it terminates as the enlarged glans penis; it is traversed by the urethra. Synonym: corpus cavernosum urethrae, spongy body of penis. Corpus spongiosum urethrae muliebris, the submucous coat of the female urethra, containing a venous network that insinuates itself between the muscular layers, giving to them an erectile nature. (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) |
