Which prefix is used to denote "surrounding" in anatomical terms?

  1. Hypo-

  2. Peri-

  3. Epi-

  4. Sub-

The correct answer is: Peri-

The prefix that denotes "surrounding" in anatomical terms is "peri-." This prefix is derived from the Greek word meaning "around" or "surrounding." In medical terminology, it is commonly used in terms such as "pericardium," which refers to the membrane surrounding the heart, and "peripheral," indicating structures that are situated away from the center, such as the peripheral nervous system that surrounds the central nervous system. The other prefixes don't convey the same meaning of 'surrounding.' For instance, "hypo-" refers to a position that is below or beneath, "epi-" suggests a position that is upon or over, and "sub-" indicates something that is beneath or under something else. These distinctions in meaning highlight why "peri-" is the correct prefix to express the concept of surrounding in anatomical terminology.
