In medical terminology, which prefix denotes a condition of being surrounded?

• A. Sub-
• B. Pre-
• C. Retro-
• D. Peri-

Answer: (D)

The prefix that denotes a condition of being surrounded is "peri-." This term originates from the Greek word meaning "around" or "surrounding." In medical terminology, it is commonly used in words such as "pericardium," which refers to the membrane surrounding the heart, and "peritoneum," which pertains to the membrane that lines the abdominal cavity and covers the abdominal organs. This prefix indicates not just proximity, but specifically the idea of encircling or encompassing a particular structure or area in the body, clarifying the relationship between tissues and organs. The other prefixes, while they might indicate different relationships or positions (such as "sub-" meaning below or beneath, "pre-" meaning before, and "retro-" indicating behind), do not convey the meaning of being surrounded. Thus, "peri-" is clearly the most appropriate choice in this context.
