Lateral flexion usually refers to the spine, or vertebral column. You can laterally flex your head, neck, or your torso (back). =answer= Lateral direction is away from the midline of the body (an imaginary line from the middle of your node to your belly button).

Lateral flexion is therefore a combination of there two movements.
