What is the term for the lateral movement of the hand toward the radius?

• A. Ulnar deviation of wrist
• B. Radial deviation of the wrist
• C. Supination
• D. Pronation

Answer: (B)

This question tests wrist deviation terminology. Movement of the hand toward the radius—the thumb side of the forearm—is called radial deviation of the wrist. The radius is the lateral bone on that side, so sliding the hand toward it is radial deviation. In contrast, moving the hand toward the ulna (the little finger side) is ulnar deviation. Supination and pronation are rotations of the forearm that turn the palm up or down, not lateral shifting toward a bone, so they don’t describe this movement.
