Explanation: 

Detailed explanation-1: -Circumduction is the movement of the limb, hand, or fingers in a circular pattern, using the sequential combination of flexion, adduction, extension, and abduction motions. Adduction, abduction, and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.

Detailed explanation-2: -Circumduction occurs when a circle is drawn by a body part, and the bone makes the shape of a cone as it moves around. It is a combination of flexion, extension, abduction and adduction. It can only truly occur at ball and socket joints at the hip and shoulder.

Detailed explanation-3: -Circumduction is the orderly combination of shoulder movements so that the hand traces a circle and the arm traces a cone. In order it is produced by shoulder flexion, abduction, extension and abduction (or the reverse).
