Which prefix means posterior?

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

Answer: (A)

Prefixes describe where a structure is located in relation to another part of the body. poster/o comes from Latin posterus meaning behind, so it marks the back or rear position—the posterior. That makes it the correct indicator for posterior.

Dist/o means distance or being farther from the point of origin (distal), not the back side. Super/o means above or upper (superior). Conjunctiv/o relates to the conjunctiva of the eye, not location on the body’s back.
