Uberon definition : the transparent anterior portion of the fibrous coat of the eye that serves as the
chief refractory structure;
Uberon synonym : cornea of camera-type eye;
Uberon related term : tunica cornea; corneas;
Uberon Taxon note : Compared to terrestial animals, the cornea of zebrafish is relatively flat. It consists
of nonpigmented, stratified squamous nonkeratinizing epithelial cells, attached to
a thick basement membrane that is considered to be analogous to the Bowman's membrane
in mammals. In fish, and aquatic vertebrates in general, the cornea plays no role
in focusing light, since it has virtually the same refractive index as water;
