Rotation around a vertical axis occurs in which plane?

Rotation around a vertical axis occurs in which plane?

• A. Transverse plane
• B. Sagittal plane
• C. Frontal plane
• D. None

Answer: (A)

Rotation around a vertical axis is a turning motion that happens in the horizontal sense. This movement lies in the transverse plane, which runs horizontally through the body and divides it into upper and lower parts. The vertical axis is perpendicular to this plane, so turning left or right occurs within that horizontal slice. In contrast, movements in the sagittal plane are flexion/extension around a front-to-back axis, and movements in the frontal plane are abduction/adduction around a side-to-side axis. So the best answer is the transverse (horizontal) plane.
