Which definition matches Abduction?

• A. Motion toward the midline
• B. Rotation of a joint
• C. Motion away from the body
• D. Bending a joint

Answer: (C)

Abduction is movement of a body part away from the midline of the body. This is what you see when you lift a limb out to the side, like raising the arm away from the torso or spreading the fingers. It contrasts with adduction (movement toward the midline), rotation (turning around an axis), and bending a joint (flexion, which changes the joint angle). So, motion away from the body’s midline best fits the definition of abduction.
