Which term is used as a prefix meaning beside or near?

The term "para-" is used as a prefix in medical terminology to denote the meanings of beside, near, or alongside. This prefix can be found in various medical terms where it indicates proximity to something. For example, "parathyroid" refers to glands located near the thyroid, and "paraplegia" refers to paralysis affecting the lower half of the body, hence indicating a condition adjacent to or near the spine.

In contrast, "inter-" refers to between or amongst, commonly used in terms like "interstate" or "intercellular." "Endo-" signifies within or inside, used in terms such as "endoscopy," which involves looking inside a body cavity. "Exo-" means outside or external, as seen in "exoskeleton," which describes a structural support located outside the body. Understanding these prefixes helps clarify the meanings in medical terminology and enhances communication in a healthcare setting.
