What's the difference between cornea and fossette?
Cornea
Definition:
(n.) The transparent part of the coat of the eyeball which covers the iris and pupil and admits light to the interior. See Eye.
Example Sentences:
(1) Displacement of the surface of the cornea of bovine eyes after disruption of intact structures was investigated by means of holographic interferometry.
(2) The patient, a 12 year-old boy, showed a soft white yellowish mycotic excrescence with clear borders which had followed the introduction of a small piece of straw into the cornea.
(3) Increased amounts of laminin in the basal epithelium of the cornea and of collagen type III in the stroma and subepithelial components of the stroma were observed.
(4) We report on a membrane inflation method of wound spreading in intact human corneas using the Baribeau Micronscope.
(5) When 5 corneas with quiescent HSK were cultured in vitro, 3 again became HSV antigen positive.

(7) The eye is of the closed vesicle type and is composed of retina, cornea, vitreous body, lens and optic nerve.
(8) The steps in the model are the drug elimination rate in the precornea and anterior chamber, the rate of drug dissolution, the rate of drug penetration into the cornea, and the rate of drug transport into the aqueous humor.
(9) Gas trapping and corneal edema were not observed in uncovered corneas or corneas covered with membrane lenses.
(10) Since lymphocytic cells in intimate contact with degenerating keratocytes have previously been identified in the cornea, these observations provide a basis for the view that cell-mediated immunopathogenesis is involved in the etiology of herpetic stromal keratitis.
(11) Lactate dehydrogenase (LDH) levels and subunit isozyme patterns in cornea were monitored in 36 albino rabbits wearing thick, rigid, gas-permeable contact lenses for periods of 24 h, 2 and 7 days, and 1 and 3 months.
(12) Calculations of energies of activation, taken from Arrhenius plots, indicate that the diffusion of drug across the cornea may be by two different mechanisms that depend on the physical-chemical characteristics of the perfusant.
(13) The mean in the newborn-to-6-month-old group was 47.59 D; in the 12-18-month-old group it had decreased to 45.56 D. The cornea appears to stabilize at about 54 months, with an average reading of 42.69 D. Evaluation of 11 eyes diagnosed as having persistent hyperplastic primary vitreous revealed that eyes with this diagnosis generally have steeper corneas than normal eyes at any given age.
(14) There was no significant difference in the wound-healing rate, but at 36 hours there was a reduction in wound-healing rate of the excimer ablated corneas.
(15) More importantly, this study reports the first detection of LAT in RNA extracted from 9% of corneas from latently infected rabbits (n = 22) by the polymerase chain reaction.
(16) Cat corneas were stored at refrigerator temperatures in M-K medium (TC-199, 5% dextran), modified M-K medium (TC-199, 1% chondroitin sulfate), or on the intact globe in moist chambers for intervals of one to nine days.
(17) Pterygia, triangular sheets of fibrovascular tissue that invade the cornea, have recurrence rates of 30% to 50% with currently available surgical procedures.
(18) Rabbit corneas grown in organ culture (24 well plate) were inoculated topically with 50 microliters (5 x 10(5) pfu) of different ocular adenoviral serotypes (ATCC and clinical isolates).
(19) A recipient cornea gradually developed wrinkling and opacification in Bowman's layer following an uneventful myopic epikeratoplasty.
(20) In neurological diseases the hyposensitivity could include the cornea, conjunctiva and lid margin.
Fossette
Definition:
(n.) A little hollow; hence, a dimple.
(n.) A small, deep-centered ulcer of the transparent cornea.
Example Sentences:
(1) Dissection and radiography of 32 injected human cerebella show that AICA and its major branches define the position of the pontomedullary sulcus; supra-olivary fossette; 5th-11th cranial nerves; brachium pontis; flocculus; great horizontal fissure; posterolateral fissure; superior semilunar lobule; inferior semilunar lobule; biventral lobule; foramen of Luschka; and the choroid plexus of the lateral recess of the 4th ventricle.
