| fissura horizontalis cerebelli | Horizontal fissure that divides the ansiform lobule into its major parts, crus I (superior semilunar lobule) and crus II (inferior semilunar lobule). Synonym: fissura horizontalis cerebelli, great horizontal fissure. (05 Mar 2000) |
| fissura prima cerebelli | The deepest fissure of the cerebellum; demarcates the division of anterior and posterior lobes of the cerebellum; second to appear embryologically. Synonym: fissura prima cerebelli. (05 Mar 2000) |
| fissura secunda cerebelli | A fissure that separates the uvula of the inferior vermis of the cerebellum from the pyramid. Synonym: fissura secunda cerebelli. (05 Mar 2000) |
| fissura transversa cerebelli | The cleft caused by the protrusion of the anterior lobe of the cerebellum over the superior and middle cerebellar peduncles. Synonym: fissura transversa cerebelli. (05 Mar 2000) |
| folia cerebelli | cerebellar folia |
| laminae albae cerebelli | Layers of white substance seen on section of the cerebellum. Synonym: laminae medullares cerebelli. (05 Mar 2000) |
| laminae medullares cerebelli | Layers of white substance seen on section of the cerebellum. Synonym: laminae medullares cerebelli. (05 Mar 2000) |
| frenulum cerebelli | A band passing from the longitudinal groove between the quadrigeminal bodies on to the superior medullary velum. Synonym: frenulum veli medullaris superioris, cerebellar frenulum, frenulum cerebelli. (05 Mar 2000) |
| lingua cerebelli | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |
| lingula cerebelli | Synonym: lingula of cerebellum. (05 Mar 2000) |
| lobulus centralis cerebelli | A division of the superior vermis of the cerebellum between the lingula and the monticulus. Synonym: lobulus centralis cerebelli, central lobule. (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) |
