Which movement decreases the angle between two adjacent body segments?

• A. Flexion
• B. Eversion
• C. Pronation
• D. Supination

Answer: (A)

Moving a joint in a way that brings the two adjacent segments closer together is flexion. When you flex a joint, the angle formed at that joint becomes smaller—for example, bending the elbow or knee brings the forearm toward the upper arm or the lower leg toward the thigh, reducing the angle between them.

Eversion is a foot movement that tilts the sole outward, which doesn’t focus on shortening the angle between two connected body segments. Pronation and supination are rotational movements of the forearm (turning the palm down or up) or of the foot, which align or rotate the segments around a axis but don’t primarily reduce the angle between two segments.
