Which axis is associated with movements in the transverse plane?

• A. Vertical axis
• B. Frontal axis
• C. Sagittal axis
• D. None

Answer: (A)

Movements in the transverse plane occur as rotations around a vertical axis. A vertical axis runs top to bottom, so turning the head left or right or twisting the torso happens around that upright line, keeping the body’s orientation while rotating horizontally. The other axes relate to rotations in their respective planes: rotating around a side-to-side axis moves in the sagittal plane (flexion/extension), and rotating around a front-to-back axis moves in the frontal plane (abduction/adduction). So the vertical axis is the one linked to transverse-plane movement.
