Chiropractic is about helping people live healthier, fuller lives. Chiropractors focus on the nervous system and painlessly, manually adjust the vertebral column to affect the nervous system. According to Gray’s Anatomy , the nervous system is the master system in the body which controls and coordinates all other systems such as respiratory, digestive, muscular, and immune.
The nervous system includes the brain, spinal cord, the spinal nerves that exit the vertebral column through openings on the side of each vertebra, and all the peripheral nerves that branch off to serve organs, tissues, blood vessels and muscles. Information from the environment, both external and internal, goes through the spine to get to the brain. In the same manner, information and decisions made in the brain go through the spine to affect certain outcomes. It is a two-way flow of information.
