Movement around the Z axis typically corresponds to which type of spinal movement?

Movement around the Z axis refers to rotation about a vertical line that runs through the body from top to bottom. In the context of spinal movement, this is characterized predominantly by rotation.

When the spine rotates, it involves a turning motion that occurs around the axis running vertically through the body. This movement can be observed when an individual twists their torso to the left or right. For instance, during activities such as swinging a golf club or throwing a ball, the spine undergoes rotation around the Z axis.

Flexion and extension typically involve movement along the X axis (forward and backward bending), while lateral flexion involves movement along the Y axis (side bending). Therefore, the option that accurately corresponds to movement around the Z axis is indeed rotation, making it the correct choice.
