Arthr(o) denotes which anatomical concept?

• A. Bone
• B. Joint
• C. Muscle
• D. Ligament

Answer: (B)

Arthr(o) signals a joint. In medical terminology, this combining form is used to name things related to joints, such as arthritis (joint inflammation), arthroscopy (examining a joint with a scope), and arthroplasty (joint replacement). It’s distinct from roots for other structures: oste(o) for bone, my(o) for muscle, and desm(o) (or related forms) for ligaments. So the concept represented by arthr(o) is the joint.
