The action of bending a limb at a joint is known as?

The action of bending a limb at a joint is referred to as flexion. This movement decreases the angle between the two parts of the limb at a joint. For example, when you bend your elbow to bring your forearm closer to your upper arm, you are performing flexion at the elbow joint. Flexion is typically contrasted with extension, which straightens the joint and increases the angle between the parts. Understanding these terms is crucial in the context of anatomy, as they describe fundamental movements in physical activity and medical evaluation.
