Wrist extension is defined as:

Wrist extension is defined as:

• A. Rotating the forearm
• B. Bending the wrist backward, away from the palm
• C. Abducting the wrist
• D. Bending the wrist toward the palm

Answer: (B)

Wrist extension is the movement that increases the angle between the hand and the forearm by bending the wrist backward, away from the palm. In plain terms, you’re moving the back of the hand toward the forearm, which is the opposite of bending the wrist toward the palm (flexion). This is distinct from rotating the forearm (twisting the radius) or moving the wrist side to side (abduction/adduction, i.e., radial or ulnar deviation).
