Which plane is involved when performing side-to-side waving movements of the hand?

• A. Coronal plane
• B. Sagittal plane
• C. Transverse plane
• D. Oblique plane

Answer: (A)

Side-to-side waving uses movements that occur in the coronal (frontal) plane. This plane runs from head to toe and divides the body into front and back; actions in this plane include moving limbs away from or toward the midline, like abduction and adduction. When you wave your hand side to side, you’re shifting it left and right in this front-back split, which corresponds to a motion around an anterior-posterior axis. The other planes describe different directions: the sagittal plane handles forward and backward motions (flexion/extension), the transverse plane handles rotation around a vertical axis, and the oblique plane covers diagonal movements. So, side-to-side waving is best described as occurring in the coronal plane.
