Which term describes straightening a joint, increasing the angle?

Explanation:
Straightening a joint means increasing the angle between the two bones that form the joint. This action is called extension. For example, moving the elbow from a bent position to a straight position increases the angle between the upper arm and forearm, which is extension. In contrast, flexion decreases that angle (like bending the elbow). Abduction describes moving a limb away from the midline, and medial is a direction term toward the body's midline, neither of which describe increasing joint angle.
