| dorsal venous arch of foot | The arch in the subcutaneous tissue of the dorsum of the foot formed by the dorsal and digital veins; it unites medially with the dorsal vein of the great toe to form the great saphenous vein, and laterally with the dorsal vein of the little toe to form the small saphenous. Synonym: arcus venosus dorsalis pedis. (05 Mar 2000) |
| dorsal venous network of foot | A superficial network of fine veins on the dorsum of the foot. Synonym: rete venosum dorsale pedis. (05 Mar 2000) |

| intermediate dorsal cutaneous nerve | <anatomy, nerve> The lateral terminal branch of the superficial peroneal nerve, supplying the dorsum of the foot and dorsal nerves to the toes (except for adjacent parts of great and second toes). Synonym: nervus cutaneus dorsalis intermedius. (05 Mar 2000) |
| lateral dorsal cutaneous nerve | <anatomy, nerve> The continuation of the sural nerve in the foot, supplying the lateral margin and dorsum. Synonym: nervus cutaneus dorsalis lateralis, dorsal lateral cutaneous nerve. (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.

| 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) |
