Which movement means moving a limb toward the midline?

• A. Adduction
• B. Abduction
• C. Rotation
• D. Circumduction

Answer: (A)

Adduction is moving a limb toward the body's midline, the imaginary line that splits the body into left and right halves. When you bring an arm down to your side or pull your knees together, you’re performing adduction. This is opposite to abduction, which moves away from the midline (like raising an arm to the side). Rotation means turning a limb around its axis, and circumduction is a circular, cone-shaped movement that combines several motions. So the action of moving toward the midline fits adduction perfectly.
