Which medical prefix indicates a position relative to the right side of the body?

The prefix "dextro-" pertains specifically to the right side of the body. This term is derived from Latin, where "dexter" means "right." In medical terminology, it is commonly used to describe structures or conditions that are situated on the right side, such as "dextrocardia," which refers to a condition where the heart is positioned more towards the right side of the thorax.

In contrast, the prefix "post-" indicates a position behind or after, "pre-" signifies before or in front of, and "ab-" refers to a position away from or out of. Each of these prefixes serves a different purpose in indicating spatial orientation in the body, thereby reinforcing why "dextro-" is the most appropriate choice when specifying a position relative to the right side.
