Which term describes movement toward the body's midline?

• A. Adduction
• B. Abduction
• C. Supination
• D. Pronation

Answer: (A)

Adduction is movement toward the body's midline. The midline is an imaginary vertical line that runs down the center of the body, and adduction brings a limb closer to that line. For example, bringing the arm from the side toward the torso or squeezing the thighs together toward the center are adduction movements. By contrast, abduction moves away from the midline (like raising the arms out to the sides). Supination and pronation involve rotating the forearm or hand (palm up for supination, palm down for pronation) and aren’t about moving toward or away from the midline. So, the term for movement toward the body's midline is adduction.
