Which term denotes the mucous membrane lining the eyelids and reflected onto the eyeball?

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

Answer: (C)

This term refers to the conjunctiva, the mucous membrane that lines the inner surface of the eyelids and reflects over to cover the eyeball. The combining form conjunctiv/o specifically means conjunctiva, which is exactly what this description describes. Dors/o means back or dorsum, which isn’t about the eyelid lining. Cyt/o means cell, not related to a membrane. Poster/o means back or posterior, also not related to the eyelid lining. So conjunctiv/o is the appropriate term.
