Which term means bone?

Which term means bone?

• A. Oste/o
• B. Endarterial
• C. Ped/o
• D. Radi/o

Answer: (A)

In medical terminology, the combining form that means bone is oste/o. This root appears in terms like osteology (the study of bones) and osteoarthritis (a joint disease involving bone), so it directly conveys the idea of bone. The other roots point to different structures or concepts: endarterial refers to the inside of an artery, ped/o relates to the foot (and by extension areas like pediatrics), and radi/o relates to X-rays, radiology, or a radius (a bone in the forearm) but not to bone in general. Therefore, oste/o is the correct root for “bone.”
