Which of the following prefixes means "above"?

The prefix that means "above" is "supra." This term is commonly used in medical and veterinary contexts to describe structures or conditions that are located above a certain point or area in the body. For example, in anatomy, "suprarenal" refers to structures located above the kidneys (renal). Understanding prefixes like "supra" is essential in veterinary medicine as it aids in describing anatomical positions and relationships between structures, enhancing communication and comprehension among veterinary professionals and their clients.

In contrast, other prefixes convey different meanings that do not match the concept of "above." For instance, "sub" refers to something that is beneath or below, while "infra" also signifies a lower position. "Meso" typically denotes something in the middle or intermediate position, which is distinct from the meaning of "above." Therefore, "supra" is the appropriate prefix to indicate a position higher than a reference point in veterinary terminology.
