What does circumduction involve?

Circumduction is a movement that combines flexion, extension, abduction, and adduction, allowing a limb to move in a circular motion. This type of motion occurs primarily at ball-and-socket joints, such as the shoulder and hip, where a limb can trace out a circular path. It is not simply a static circular motion but incorporates various movements to achieve a 360-degree range, enabling the limb to move around a central point while maintaining the stability of the joint involved. This makes the correct choice both accurate and descriptive of the unique characteristics of circumduction. Other options describe movement types that do not accurately encompass the full scope and nature of circumduction.
