What is the act of bending a joint called?

Explanation:
Flexion is bending a joint, which decreases the angle between the two bones that form the joint. Think of curling the elbow or knee—the bones move closer together as the limb flexes. This contrasts with extension, which straightens the limb and increases that angle. Rotation refers to turning a bone around its axis, not bending, and abduction means moving a limb away from the body's midline. So the act of bending a joint is flexion.
