Which term describes a movement that combines flexion, extension, abduction, and adduction?

• A. Flexion
• B. Abduction
• C. Rotation
• D. Circumduction

Answer: (D)

Circumduction is a circular, cone-shaped movement that combines flexion, extension, abduction, and adduction. It happens when a limb moves through these directions in sequence, allowing the distal end to trace a circle while the proximal joint stays relatively fixed. For example, at the shoulder or hip, you can move the arm or leg forward (flexion), away from the body (abduction), backward (extension), and toward the body (adduction) in a continuous path, creating a circular motion. In contrast, rotation involves turning around an axis without necessarily changing the limb’s position in those four directions, and the other terms describe single movements rather than a combined circular path.
