Question

Quizplus · Accepted Answer

Abduction refers to movement away from the midline of the body, which is what occurs during jumping jacks when the arms and legs move laterally. Extension refers to straightening a joint, flexion refers to bending a joint, adduction refers to movement towards the midline of the body, and circumduction refers to a circular motion of a limb. None of these movements accurately describe the motion of jumping jacks.
