What term describes a decrease in the angle at a joint?

• A. Extension
• B. Flexion
• C. Rotation
• D. Circumduction

Answer: (B)

Decreasing the angle at a joint happens when you bend it, bringing the bones closer together. This movement is called flexion. For example, bending the elbow reduces the angle between the upper arm and the forearm. Extending the joint straightens it and increases the angle, while rotation is turning a part around its axis, and circumduction is a circular movement combining several motions. So the term for a decrease in joint angle is flexion.
