Question

Epithelial lining of cornea is composed of ................... epithelium.

• A. Non-keratinised stratified squamous
• B. Transitional
• C. Simple cubiodal
• D. Simple squamous

Answer 1

Answer: (A)

A stratified squamous epithelium consists of epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane while the other layers are adhered to one another to maintain structural integrity. There are no intercellular spaces. Non-keratinized surfaces must be kept moist by bodily secretions to prevent them from drying out. Examples of non-keratinized stratified squamous epithelium include cornea, lining mucosa of the oral cavity, esophagus, anal canal, vagina and the internal portion of the lips.

Hence the correct option is A.
