What is the term used for "rib" in medical vocabulary?

The term "cost" is derived from the Latin word "costa," which specifically refers to the rib. In anatomical terminology, "costal" pertains to the ribs, linking this word to various medical terms associated with rib-related structures and conditions. For example, phrases like "costochondritis" refer to inflammation of the cartilage that connects the ribs to the sternum.

The other terms do not pertain to ribs: "dys" typically refers to difficulty or abnormality, "hepat" relates to the liver, and "osteo" refers to bone. Each of these prefixes or roots is used in medical terminology to denote specific organs or issues but does not connect to the function or structure of ribs.
