| lamina cribrosa ossis ethmoidalis | A horizontal lamina from which are suspended the labyrinth, on either side, and the lamina perpendicularis in the centre; it fits into the ethmoidal notch of the frontal bone and supports the olfactory lobes of the cerebrum, being pierced with numerous openings for the passage of the olfactory nerves. Synonym: lamina cribrosa ossis ethmoidalis, cribrum, sieve bone, sieve plate. (05 Mar 2000) |
| lamina horizontalis ossis palatini | The part of the palatine bone that forms the posterior part (approximately one third) of the bony palate. Synonym: lamina horizontalis ossis palatini. (05 Mar 2000) |
| lamina orbitalis ossis ethmoidalis | A thin plate of ethmoid bone forming part of the medial wall of the orbit and the lateral wall for the ethmoidal labyrinth. Synonym: lamina orbitalis ossis ethmoidalis, lamina papyracea, orbital lamina of ethmoid bone, orbital layer of ethmoid bone, orbital plate, paper plate, papyraceous plate. (05 Mar 2000) |
| lamina perpendicularis ossis ethmoidalis | A thin plate of bone projecting downward from the crista galli of the ethmoid; it forms part of the nasal septum. Synonym: lamina perpendicularis ossis ethmoidalis. (05 Mar 2000) |
| lamina perpendicularis ossis palatini | The part of the palatine bone that extends vertically upward from the horizontal lamina; it forms part of the lateral wall of the nasal cavity. Synonym: lamina perpendicularis ossis palatini. (05 Mar 2000) |
| foramen caecum ossis frontalis | <anatomy> Blind or caecal foramen of the frontal bone; the blind foramen formed immediately anterior to the crista galli by a notch at the lower end of the frontal crest and its articulation with the ethmoid bone. It is insignificant postnatally, but gives passage to vessels during development. Synonym: foramen caecum ossis frontalis, blind foramen of frontal bone, caecal foramen of frontal bone. (05 Mar 2000) |
| fovea capitis ossis femoris | A depression on the extremity of the head of the femur giving attachment to the ligamentum teres femoris. Synonym: fovea capitis ossis femoris, pit of head of femur. (05 Mar 2000) |
| linea arcuata ossis ilii | The iliac portion of the linea terminalis of the bony pelvis. Synonym: linea arcuata ossis ilii. (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.
