The body is intelligent and can heal itself. From this idea chiropractic has evolved around an art, a science and a philosophy. Our brain and the nervous system control the body, our body gives back information to the brain. So they depend on each other for us to be healthy. The brain and the medulum are protected by the skull and the spine. The nerves leaving the spine go to all the systems of the body. The organs, the glance, the mussels, etc. An imbalanced body is the sign of a dysfunction.
