What is the adjective form of epiphysis?

• A. Epiphysial
• B. Metaphyseal
• C. Epiphyseal
• D. Physeal

Answer: (C)

The main idea is how anatomical regions of a bone get their descriptive adjective. Epiphysis means the end part of a long bone, so the adjective that specifically denotes something relating to that end is epiphyseal. This form is standard in anatomy and appears in phrases like the epiphyseal plate, epiphyseal cartilage, and epiphyseal line. A variant spelling, epiphysial, exists but epiphyseal is the preferred and most widely used form. Metaphyseal would describe the metaphysis (the region between the growth plate and the shaft), and physeal refers to the physis or growth plate itself, not the epiphysis. So epiphyseal is the correct term.
