Which prefix means above or superior?

• A. poster/o
• B. super/o
• C. dist/o
• D. conjunctiv/o

Answer: (B)

Above or superior is conveyed in medical terms by the combining form super/o. This form literally means above or on top, so it’s used to express a position higher than something else or a higher level in the body. The other forms point to different directions or regions: poster/o means back (posterior), dist/o means distant or away from the point of origin (distal), and conjunctiv/o relates to the conjunctiva of the eye. Hence, super/o is the one that carries the meaning of above.
