The mucous membrane that covers the front of the eye and lines the inside of the eyelids is called?

• A. Cornea
• B. Conjunctiva
• C. Iris
• D. Retina

Answer: (B)

The conjunctiva is the mucous membrane that covers the front of the eye and lines the inside of the eyelids. It’s a thin, moist tissue that helps keep the eye lubricated and provides a barrier against dirt and infection. It forms the conjunctival sac between the eyelids and the eyeball and includes both the part that covers the eyeball (bulbar conjunctiva) and the part that lines the lids (palpebral conjunctiva). The cornea is the clear front window of the eye, the iris is the colored part that controls light entry, and the retina is the light-sensitive layer at the back of the eye; none of these are the mucous membrane described.
