To understand how upper cervical care works, one must first understand how the nervous system (brain and spinal cord) functions. The human brain communicates through a large network of nerves (similar to an electrical circuit) connecting different organs and systems of the body (like telephone wires connecting phones). This constant communication is essential for the proper function and health of every cell, organ, and system in the body.
The spinal cord transmits information back and forth between the brain and the body and is protected by the spinal column. When injuries occur to spinal segments (traumas such as auto accidents, falls, sports accidents, the birth process, etc.), the spinal vertebrae may misalign and irritate surrounding nerves, resulting in a "short circuit" of the involved nerves.
The top two bones in the neck have been isolated as the most significant in the spinal column because these vertebrae are located at the critical junction between the brain (control center) and the spinal cord.
Because the nervous system controls and coordinates all functions in our bodies, including our immune system, any misalignments causing irritation to the nerves at this critical level in the upper cervical spine can result in dysfunction of the bodily organs supplied by the damaged nerves, thus creating numerous health problems. Because all nerve signals must pass through the upper cervical region in order to reach lower parts of the body, any and all functions of the body can be affected by the spine at this level. Upper cervical care aims to eliminate neurological irritation; because without irritation, our nervous systems can properly control our bodies' functions and maintain us in good health.
