| 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 luysi | A circumscript nucleus, shaped like a biconvex lens, located in the ventral part of the subthalamus on the dorsal surface of the peduncular part of the internal capsule immediately rostral to the substantia nigra. The nucleus receives a massive topographic projection from the lateral segment of the globus pallidus, and a somatopically organised projection from the ipsilateral motor cortex; a smaller bundle of afferents from the centromedian nucleus of the thalamus terminate in the rostral part of the nucleus The subthalamic nucleus projects to both pallidal segments, to the pars reticulata of the substantia nigra, and in a small way to the ipsilateral pedunculopontine nucleus. Synonym: nucleus subthalamicus, corpus luysi, Luys' body, nucleus of Luys. (05 Mar 2000) |
| corpus mamillare | A small, round, paired cell group that protrudes into the interpeduncular fossa from the inferior aspect of the hypothalamus. It receives hippocampal fibres through the fornix and projects fibres to the anterior thalamic nuclei and into the brainstem tegmentum. Synonym: corpus mamillare, mamillary tubercle of hypothalamus. (05 Mar 2000) |
| corpus mammae | The principal part of the breast, consisting of glandular tissue and its supporting fibrous tissue. It forms a conical mass converging toward the nipple and is surrounded by adipose tissue. Synonym: corpus mammae. (05 Mar 2000) |
| corpus mandibulae | The heavy, U-shaped, horizontal portion of the mandible extending posteriorly to the angle where it is continuous with the ramus; it supports the lower teeth. Synonym: corpus mandibulae. (05 Mar 2000) |
| corpus maxillae | The central portion of the maxilla hollowed out by the maxillary sinus; it presents orbital, nasal, anterior, and infratemporal surfaces and supports four processes, frontal, zygomatic, palatine, and alveolar. Synonym: corpus maxillae. (05 Mar 2000) |
