Which term lines eyelids mucous membrane?

• A. cerebell/o
• B. conjunctiv/o
• C. dors/o
• D. cyt/o

Answer: (B)

Conjunctiv/o is the combining form for conjunctiva, the mucous membrane that lines the inside of the eyelids (palpebral conjunctiva) and covers the white of the eye (bulbar conjunctiva). This membrane keeps the eye moist and serves as a protective barrier. Other roots don’t fit because cerebell/o relates to the cerebellum in the brain, dors/o means back or dorsal, and cyt/o refers to a cell—none of these pertain to the eyelid lining.
