The membranous tissue that lines the eyelids and covers the sclera is called what?

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

Answer: (A)

The conjunctiva is the thin mucous membrane that lines the inside of the eyelids and covers the white part of the eye (the sclera). It keeps the eye moist with mucus and provides a protective barrier against dust and pathogens. It’s not the retina, which is the light-detecting layer at the back of the eye; not the sclera, which is the tough white outer coat; and not the cornea, which is the clear front surface that refracts light.
