| corpus geniculatum externum | The lateral one of a pair of small oval masses that protrude slightly from the posteroinferior aspects of the thalamus; its main (dorsal) subdivision serves as a processing station in the major pathway from the retina to the cerebral cortex, receiving fibres from the optic tract and giving rise to the geniculocalcarine radiation to the visual cortex in the occipital lobe. Synonym: corpus geniculatum laterale, corpus geniculatum externum. (05 Mar 2000) |
|---|---|
| corpus geniculatum internum | The medial one of a pair of prominent cell groups in the posteroinferior parts of the thalamus; it functions as the last of a series of processing stations along the auditory conduction pathway to the cerebral cortex, receiving the brachium of the inferior colliculus and giving rise to the auditory radiation to the auditory cortex in the superior temporal gyrus. Synonym: corpus geniculatum mediale, corpus geniculatum internum. (05 Mar 2000) |

Synonym: corpus geniculatum mediale, corpus geniculatum internum. (05 Mar 2000) |
| corpus glandulae sudoriferae | The coiled tubular secretory portion of a sweat gland located in the subcutaneous tissue or deep in the corium and connected to the surface of the skin by a long duct. Synonym: corpus glandulae sudoriferae. (05 Mar 2000) |
| corpus haemorrhagicum | A haematoma with a lining formed by the thinned-out bright yellow lutein zone; gradual resorption of the blood elements leaves a cavity filled with a clear fluid, i.e., a corpus luteum cyst. Synonym: corpus luteum haematoma. (05 Mar 2000) |
| corpus highmorianum | A mass of fibrous tissue continuous with the tunica albuginea, projecting into the testis from its posterior border. Synonym: corpus highmori, corpus highmorianum, Highmore's body, septum of testis. (05 Mar 2000) |
| corpus humeri | The elongated rod-like portion of the humerus between the surgical neck proximally and the emergence of the supracondylar ridges distally. Synonym: corpus humeri. (05 Mar 2000) |
| corpus incudis | The main part of the incus that articulates with the malleus and from which the short and long limbs arise. Synonym: corpus incudis. (05 Mar 2000) |
| corpus linguae | The oral part of the tongue anterior to the terminal sulcus. Synonym: corpus linguae. (05 Mar 2000) |
| corpus luteum | <gynaecology> A yellow glandular mass in the ovary formed by an ovarian follicle that has matured and discharged its ovum. The corpus luteum secretes progesterone. If the ovum has been impregnated, the corpus luteum increases in size and persists for several months (corpus luteum graviditatis). If impregnation has not taken place, the corpus luteum degenerates and shrinks (corpus luteum menstruationis). Synonym: yellow body of ovary. (13 Nov 1997) |
| corpus luteum deficiency syndrome | <syndrome> Functional disturbances caused by insufficient ovarian luteinization; reflected by inadequate luteal phase endometrial response. (05 Mar 2000) |
| corpus luteum haematoma | A haematoma with a lining formed by the thinned-out bright yellow lutein zone; gradual resorption of the blood elements leaves a cavity filled with a clear fluid, i.e., a corpus luteum cyst. Synonym: corpus luteum haematoma. (05 Mar 2000) |
| corpus luteum hormone | <biochemistry, gynaecology> Produced in the corpus luteum, as an antagonist of oestrogens. Promotes proliferation of uterine mucosa and the implantation of the blastocyst, prevents further follicular development. (18 Nov 1997) |
| corpus luteum hormone unit | The progestational activity of 1 mg of unit of progestational activity; standard preparation of pure progesterone. See: Clauberg test, Corner-Allen unit. Synonym: corpus luteum hormone unit, unit of luteinizing activity. (05 Mar 2000) |
