What is the anatomical position?

• A. The position standing erect with feet slightly separated and palms facing anteriorly
• B. The position lying on the back with arms at sides
• C. The position standing with feet together and arms crossed
• D. The position squatting with palms on thighs

Answer: (A)

The anatomical position is the standard posture used to describe locations on the body. In this position a person stands erect with feet either together or slightly apart, the arms at the sides, and the palms facing forward (anteriorly). This setup aligns the body so that directional terms like anterior vs posterior and medial vs lateral have a consistent frame of reference, and it keeps the forearms in a position where the thumbs point away from the body.

The description that matches this posture is standing upright with feet slightly apart and the palms facing forward, which corresponds to the conventional anatomical position. Other described postures—lying on the back with arms at the sides, standing with feet together and arms crossed, or squatting with palms on the thighs—do not establish the standard orientation of surfaces and limbs used for anatomical directions.
