What movement occurs when a bone is moved away from the midline of the body?

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

Answer: (C)

Abduction is the movement of a limb away from the body's midline. When a bone or limb is moved laterally away from the center, you’re performing abduction. For example, raising the arm out to the side or moving the leg away from the midline of the body illustrates this action. Muscles like the deltoid and supraspinatus help abduct the shoulder, while the gluteus medius abducts the hip. The opposite action is adduction, which brings the limb toward the midline. Other terms like rotation or flexion describe different directions or types of joint movement, not this side-to-side, midline-walking description.
