What is the term for the lateral movement of the wrist toward the little finger side?

• A. Radial deviation
• B. Ulnar deviation
• C. Circumduction
• D. Flexion

Answer: (B)

The lateral movement of the wrist toward the little finger side is called ulnar deviation. The term “ulnar” points to the ulna—the bone on the little finger side of the forearm. So when the wrist tilts toward that pinky side, the movement is ulnar deviation. The opposite direction, toward the thumb side, is radial deviation. Circumduction describes a circular, combined set of movements, not a single lateral deviation, and flexion is bending that reduces the angle between the palm and forearm.
