Movement toward the body's midline is called?

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

Answer: (A)

Movement toward the body's midline is named adduction. This describes bringing a limb or part of the body closer to the centerline, such as pulling an arm in toward the torso or bringing the legs together at the midline. In contrast, moving away from the midline is abduction, like raising the arms out to the sides. Flexion and extension refer to changing the angle of a joint—flexion bends the joint (decreasing the angle), and extension straightens it (increasing the angle). So, the action described as moving toward the midline fits adduction most closely.
