In the anatomical position, which direction describes the palms?

• A. Facing backward
• B. Facing forward
• C. Facing inward toward the body
• D. Facing downward

Answer: (B)

In anatomy, the standard reference position has you standing upright with your arms at your sides and your palms facing forward. This orientation uses forward-facing palms as the baseline, which is why the correct description is palms facing forward. The forward position occurs because the forearms are in a supinated, or resting, orientation with the radius and ulna parallel, so the palms point toward the front of the body. The other descriptions correspond to different arm rotations: palms facing backward would be the forearms rotated so the palms point to the back; palms facing downward describes a palms-down or pronated position; palms facing inward toward the body would mean turning the palms toward the midline, which is not the standard reference.
