Prefix indicating posterior, situated behind or towards the back.

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

Answer: (A)

In medical terminology, location prefixes tell you where something is. The prefix poster/o- designates the back side. That means it’s used to describe structures toward the back, i.e., posterior. For example, terms like posterolateral combine this backward-direction sense with other directions to describe a position at the back and side.

The other options point to different ideas: super/o- means above or upper, dist/o- relates to distance from a point of origin (distal), and cerebell/o- refers to the cerebellum, a brain region—not a prefix that indicates back location.
