Abduction and Adduction describe which movement?

• A. Rotation.
• B. Movement toward the midline.
• C. Flexion and extension.
• D. Movement away/into from midline.

Answer: (D)

Abduction and adduction describe movements relative to the body's midline. Abduction moves a limb away from the midline, while adduction moves it toward the midline. So these terms collectively refer to moving toward or away from the midline, rather than rotation (turning around an axis) or flexion/extension (bending and straightening).
