What is the term for moving a body part away from the midline of the body?

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

Answer: (C)

The term for moving a body part away from the midline of the body is abduction. This action involves increasing the angle between a body part and the midline, effectively drawing the limb or body part outward. This movement is commonly seen in actions such as raising the arms to the side or spreading the fingers apart. In contrast, adduction refers to the movement toward the midline, which would decrease the angle between body parts. Flexion involves decreasing the angle at a joint, meaning bending a limb or a body part. Extension is the opposite of flexion; it involves straightening a limb or body part. Therefore, abduction specifically describes the outward movement away from the body’s center line, making it the correct choice.
