Which term is the outer surface of the cornea comprised of cells that regenerate continuously?

• A. Epithelium
• B. Epithelial defect
• C. Evisceration
• D. Forceps

Answer: (A)

The outer surface of the cornea is covered by epithelium, a stratified squamous layer that regenerates continuously. Basal cells divide to replace superficial cells worn away by blinking and the tear film, keeping the surface smooth and transparent for clear vision. An epithelial defect would describe a loss or damage to this layer, not the tissue itself. Evisceration is the surgical removal of eye contents, and forceps are surgical instruments—both unrelated to the corneal surface structure. So, the term that best fits the description is epithelium.
