Which term describes increasing the angle of a joint?

Explanation:
Increasing the angle between two bones is extension. This motion straightens a limb or opens a joint, moving from a bent position toward a greater separation of the bones. In the elbow, for example, extending straightens the elbow and increases the angle between the upper arm and forearm. Flexion does the opposite, bending to decrease the angle. Circumduction rotates the limb in a circular path, combining several movements, while rotation is turning a body part around its axis. So the term that describes increasing the angle is extension.
