Which term decreases the angle of the joint and brings two bones closer together?

• A. Flexion
• B. Extension
• C. Elevation
• D. Dorsiflexion

Answer: (A)

Flexion is the movement that decreases the angle between two bones at a joint, bringing them closer together. This happens when you bend a limb at the elbow or knee, or curl a finger toward the palm, shortening the angle between the connected bones. In contrast, extension straightens the joint and increases that angle. Elevation involves lifting a body part upward and doesn’t inherently change the joint angle. Dorsiflexion is a specific ankle movement where the foot moves toward the shin; while it also reduces the angle at the ankle, the broader term that describes the action of bringing bones closer together at a joint is flexion.
