<prompt> Cornea is lined by -Ciliated columinarSimple columinarSquamous non-keratisizedPseudostrati fied  <response>: Ans. is c i.e., Squamous non-keratisized Histology of corneao The cornea has five distinct layers from superficial to deep: -Epithelium : - It is the outermost part of cornea and is composed of stratified squamous non-keratinized epithelial cellsQ.Bowmans membrane : - It is not a true membrane but simply a condensed superficial part of stroma. Once destroyed, it does not regenerateQ.Stroma Substantia propria : - This layer constitutes most of the cornea 90 of thickness. It consists of collagen fibrils lamellae embedded in hydrated matrix of proteoglycans.Descemets membrane : - This layer bounds the stroma posteriorly. In the periphery it appears to end at the anterior limit of trabecular meshwork as Schwableys ring.Endothelium : - It is a single layer of flat polygnonal cells. The endothelial cells contain active-pump mechanism and is the most important layer in maintaining the transparency of corneaQ.
