Axial rotation occurs in which plane?

The correct answer is the transverse plane, as axial rotation refers to the movement of a body segment around its longitudinal axis. This plane is positioned horizontally, dividing the body into upper and lower sections. When movements such as twisting or rotating occur, they take place in this plane, enabling actions like turning the head or rotating the trunk.

Understanding the planes of motion is crucial in biomechanics because different movements are categorized based on the plane in which they occur. The transverse plane specifically encompasses rotational movements, making it the correct choice in this context. The other planes—coronal, sagittal, and frontal—are associated with different types of movements; for instance, the sagittal plane involves flexion and extension, while the coronal plane encompasses abduction and adduction.
