Which combining form corresponds to the ankle?

The combining form that corresponds to the ankle is "tars/o." This term is derived from "tarsus," which refers to the collection of bones that make up the ankle joint. In medical terminology, combining forms are created when a root word is combined with a suffix or prefix, and "tars/o" specifically pertains to the bony structure of the ankle.

Understanding medical terminology is crucial for a Certified Medical Assistant, as it aids in clear communication with healthcare professionals and accurate documentation in patient records. The other combining forms listed—such as "hist/o" (related to tissue), "esophag/o" (pertaining to the esophagus), and "ventr/i" (referring to the ventral or front side of the body)—apply to different anatomical structures, which is why they are not relevant to the question regarding the ankle.
