Descriptor córnea
Scope note: Porción anterior y transparente de la cubierta fibrosa del ojo constituida por cinco capas: epitelio escamoso estratificado (epitelio anterior), la LÁMINA LIMITANTE ANTERIOR (membrana de Bowman), el estroma (sustancia propia, tela conectiva), LÁMINA LIMITANTE POSTERIOR (membrana de Descemet) y el endotelio mesenquimatoso (mesotelio). Funciona como el primer medio de refracción del ojo. Estructuralmente se continua con la esclera, es avascular, y recibe su nutrición por permeabilidad a través de los espacios existentes entre las láminas. Está inervada por la división oftálmica del nervio trigémino, a través de los nervios ciliares y los de la conjuntiva que la rodea que conjuntamente forman plexos.

Scope note: The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)
