Movements such as abduction/adduction, lateral flexion, ulnar/radial deviation, and eversion/inversion occur in which plane?

• A. Transverse Plane Movements
• B. Sagittal Plane Movements
• C. Oblique Plane Movements
• D. Frontal Plane Movements

Answer: (D)

These movements happen in the frontal plane because they involve moving body parts side to side relative to the midline—abduction and adduction move away from or toward the midline, lateral flexion tilts the spine to the side, and wrist or ankle deviations and foot eversion/inversion shift parts toward the outer edges of the body. The frontal plane divides the body into front and back sections, and rotations occur around an anterior-posterior axis within this plane. In contrast, flexion/extension occur in the sagittal plane, rotation in the transverse plane, and the oblique plane describes mixed-plane movements, so the listed motions fit best with frontal plane movements.
