Wrist flexion is defined as:

• A. Straightening the wrist
• B. Rotating the wrist medially
• C. Bending the wrist toward the palm
• D. Abducting the wrist

Answer: (C)

Wrist flexion means bending the wrist so the palm moves toward the forearm. In anatomical terms, this decreases the angle between the hand and the forearm, and is called palmar (volar) flexion. The opposite motion is extension, which straightens the wrist and increases that angle. Rotating the forearm medially relates to pronation and isn’t the same as bending the wrist. Abducting the wrist refers to radial deviation, moving the hand sideways toward the thumb, not toward the palm. So bending toward the palm best fits wrist flexion.
