| folliculi glandulae thyroideae | <physiology> The small spherical vesicular components of the thyroid gland lined with epithelium and containing colloid in varying amounts. The colloid serves for storage of the thyroid hormone precursor, thyroglobulin. Synonym: follicles of thyroid gland. Origin: L. A small sac, dim. Of follis, bellows (05 Mar 2000) |

| fossa glandulae lacrimalis | A hollow in the orbital plate of the frontal bone, formed by the overhanging margin and zygomatic process, lodging the lacrimal gland. Synonym: fossa glandulae lacrimalis, fossa of lacrimal gland. (05 Mar 2000) |
| lobi glandulae mammariae | The 15 to 20 separate portions of the mammary gland that radiate from the central area deep to the nipple like wheel spokes and comprise the body of the mammary gland; each is drained by a single lactiferous duct. Synonym: lobi glandulae mammariae. (05 Mar 2000) |
| lobi glandulae thyroideae | The two major divisions of the gland lying on the right and left side of the trachea and connected by the isthmus. A smaller pyramidal lobe is frequently present as an upward extension from the isthmus. Synonym: lobi glandulae thyroideae. (05 Mar 2000) |
| lobuli glandulae mammariae | Subdivisions of the lobes of the mammary gland. Synonym: lobuli glandulae mammariae. (05 Mar 2000) |
| lobuli glandulae thyroideae | The subdivisions of the lobes, consisting of incompletely separated, irregular groups of thyroid follicles (20 to 40 in number) bound together by delicate connective tissue. Synonym: lobuli glandulae thyroideae. (05 Mar 2000) |
| lobus pyramidalis glandulae thyroideae | <anatomy> An inconstant narrow lobe of the thyroid gland that arises from the upper border of the isthmus and extends upward, sometimes as far as the hyoid bone; it marks the point of continuity with the thyroglossal duct. Synonym: lobus pyramidalis glandulae thyroideae, Lallouette's pyramid, Morgagni's appendix, pyramid of thyroid. (05 Mar 2000) |
| agenesis of corpus callosum | <radiology> Defect in dorsal portion of lamina reuniens, occurs about 10th - 12th week of gestation, may be complete or partial CT findings: parallel lateral ventricles, occipital horns dilated, deep falx, frontal horns C-shaped on coronal view associated with, Dandy-Walker cyst, encephalocele, Arnold-Chiari malformation, CNS lipoma (12 Dec 1998) |
| atretic corpus luteum | 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) |
| bulb of corpus spongiosum | The expanded posterior part of the corpus spongiosum of the penis lying in the interval between the crura of the penis. Synonym: bulbus penis, bulb of corpus spongiosum, bulb of urethra, bulbus urethrae. (05 Mar 2000) |
| radiation of corpus callosum | The spreading out of the fibres of the corpus callosum in the centrum semiovale of each cerebral hemisphere. Synonym: radiatio corporis callosi. (05 Mar 2000) |
| vein of corpus striatum | <anatomy, vein> A long vein passing forward in the groove between the thalamus and caudate nucleus, covered by the lamina affixa, receiving the transverse caudate veins along its lateral side, and joining at the caudal wall of Monro's foramen with the choroidal vein and vein of septum pellucidum to form the internal cerebral vein. Synonym: vena terminalis, vena thalamostriata superior, terminal vein, vein of corpus striatum. (05 Mar 2000) |
| genu of corpus callosum | The anterior extremity of the corpus callosum that folds downward and backward on itself, terminating in the rostrum. Synonym: genu corporis callosi. (05 Mar 2000) |
| parenchymatous cell of corpus pineale | A cell of the pineal body with long processes ending in bulbous expansions. Pinealocytes receive a direct innervation from sympathetic neurons that form recognizable synapses. The club-shaped endings of pinealocyte processes terminate in perivascular spaces surrounding capillaries. Synonym: chief cell of corpus pineale, parenchymatous cell of corpus pineale. Origin: pineal + G. Kytos, cell (05 Mar 2000) |
| caverns of corpus spongiosum | The vascular spaces forming the erectile tissue of the corpus spongiosum penis in the male and the bulb of the vestibule in the female. Synonym: cavernae corporis spongiosi, cavities of corpus spongiosum. (05 Mar 2000) |
