Which term describes bending the trunk sideways away from the midline?

• A. Lateral Flexion
• B. Horizontal Adduction
• C. Rotation
• D. Circumduction

Answer: (A)

Lateral flexion describes bending the trunk or neck sideways away from the midline, in the frontal plane. It’s the movement you use when tilting your head toward a shoulder or leaning to the side at the waist. Horizontal adduction would move a limb toward the midline in the horizontal plane, rotation twists around the body's axis, and circumduction combines flexion, abduction, extension and adduction into a circular motion. So the sideward bend of the trunk is lateral flexion.
