Which term is represented by a check mark?

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

Answer: (C)

Flexion is the movement shown by a check mark. It means bending a joint so the angle between the two body parts decreases. For example, bending the elbow brings the forearm toward the upper arm, reducing the joint angle. The other motions are different: extension straightens the joint and increases the angle; abduction moves a limb away from the body's midline; rotation involves turning a part around its own long axis. So the check-marked position represents flexion.
