Final answer:
The suffix -ior is used to indicate 'pertaining to', but to convey the meaning of 'pertaining to the front', the correct anatomical term is simply 'anterior'. While 'anteriorior' is not a recognized medical term, 'anterior' is universally accepted and understood in medical contexts.
Step-by-step explanation:
To build a medical term meaning "pertaining to the front" using the suffix -ior, we need to consider the directional term that refers to the front of the body. In anatomical terms, anterior (or ventral) describes the front or direction toward the front of the body.
Therefore, the medical term created by adding the suffix -ior, which indicates 'pertaining to', to the word anterior gives us anteriorior. However, it should be noted that anteriorior is not a standard medical term. The proper term for 'pertaining to the front' is simply anterior. In medical contexts, terms are standardized, and anterior is the accepted terminology without the need for additional suffixes like -ior.
Anatomical terms like anterior come from Ancient Greek and Latin roots, and are used in conjunction with the standard anatomical position to describe the relative locations of body structures precisely. This ensures consistency and clarity in medical communication, making it crucial to abide by these established terms.
