What is abduction?

Explanation:
Abduction is the movement of a body part away from the midline of the body. For example, lifting the arm out to the side or spreading the fingers apart moves away from the central line that runs down the center of the body. This contrasts with adduction, which brings a limb toward the midline. Circumduction is a circular, cone-shaped motion that combines several movements (flexion, extension, abduction, and adduction), and rotation is turning a part around its own long axis. So moving away from the midline accurately defines abduction.
