Which term describes a movement that increases the angle between two bones at a joint?

Explanation:
Extension describes increasing the angle between two bones at a joint. When you straighten a bent elbow or knee, the angle between the two bones becomes larger, moving toward a straight alignment. Flexion does the opposite, reducing that angle by bending the joint. Pronation and supination are rotational movements of the forearm that turn the palm and do not primarily change the angle between the two bones at the joint.
