Stabilization of the head and neck is a "mission critical" function. The head is a platform for the eyes and ears, and controlling it's motion is critical to interpreting information from these senses. When the head is uncontrolled (such as in a motor vehicle accident), serious injury may result. The head and neck in the upright position are intrinsically unstable and would fall over without stabilization.
