Chiropractic is a healing art that recognizes the nervous system as the primary determining factor of a person’s health. The human nervous system regulates all life-sustaining functions such as movement, blood circulation, digestion, breathing, and immunity from disease. The nervous system is comprised of the brain and spinal cord, which resides inside the spine. Nerves branch out from the spinal cord, exit from between the bones of the spine (vertebrae), and divide numerous times until every cell in the body is reached. Nerves are like electrical wires that run through our body, and the brain is like a “generator” sending electrical impulses through these nerves to every single cell, telling them what to do. Thanks to this miraculous system, living in good health is possible-our digestive system automatically converts our meals into living tissue; our lungs automatically take in and extract oxygen from air; cuts and wounds automatically heal; and invading germs are automatically attacked and destroyed. Whenever the nervous system is functioning properly, optimum health is possible.
