Which movement moves toward the body's midline?

Which movement moves toward the body's midline?

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

Answer: (B)

Adduction is the movement toward the body's midline. The midline is the imaginary center line that runs down the body, so when a limb is moved from the side back toward that line—like bringing the arms down to the sides of the body or squeezing the legs together—you’re adducting. This is the opposite of abduction, which moves away from the midline. Circumduction describes a circular path that combines several movements, so it isn’t specifically about moving toward or away from the midline. Rotation involves turning a bone around its long axis, which also doesn’t target the midline movement.
