What describes flexion?

Explanation:
Flexion is bending a joint to decrease the angle between the two bones at that joint. This is exactly described by bringing the bones closer together, which occurs when the angle is reduced, such as bending the elbow or knee. The other movements aren’t flexion: increasing the angle at a joint is extension; rotation involves turning a bone around its axis without necessarily changing the joint angle; circumduction is a circular, cone-like movement that combines several actions. So the description of decreasing the joint angle and bringing the two bones closer best captures what flexion is.
