Which term describes movement that decreases the angle of a joint?

• A. Flexion
• B. Dorsiflexion
• C. Elevation
• D. External rotation

Answer: (A)

Flexion is the movement that decreases the angle between two bones at a joint. When you bend a joint, like the elbow or knee, the bones move closer together and the angle between them gets smaller, which is flexion. Dorsiflexion is a specific type of flexion at the ankle where the foot moves upward toward the shin; elevation refers to lifting a body part straight up, and external rotation is turning a limb outward around its axis. Because flexion describes the general action of reducing a joint angle, it’s the best term for this concept.
