What does "infra" refer to in medical terminology?

In medical terminology, "infra" is derived from Latin, meaning "below" or "beneath." This term is often used in anatomical contexts to specify the location of a structure in relation to another. For example, in phrases such as "infrastructure" or "infrapatellar," it indicates that something is situated beneath or lower than a referenced point or structure.

Understanding the meaning of "infra" is important for medical professionals and interpreters, as it helps accurately convey locations and relationships of anatomical parts during communication. Other terms in medical language can involve directional cues, but "infra" distinctly communicates a position that is lower or beneath something else.
