What term describes an increase in the angle at a joint?

Explanation:
When a joint straightens, the angle between the two bones increases. This action is called extension. Flexion, in contrast, bends the joint and reduces the angle. Adduction and abduction describe movements toward or away from the midline, not changes in the joint angle. For example, straightening the elbow or knee increases the angle, while bending it decreases the angle. So the term that describes an increase in the angle at a joint is extension.
