An aftermovement is the movement of a limb following the contraction of a muscle.
circumduction
The circular movement at the far end of a limb is called circumduction. This movement involves a combination of flexion, extension, abduction, and adduction in a circular pattern. It allows for a wide range of motion in the joint.
