The Nervous System
Our system of nerves in our bodies is the control system of all function. In development, the nervous system is the first structure to develop namely the primitive streak. This becomes our central nervous system. It is highly complicated and extremely sensitive. Protecting these structures namely the brain and the spinal cord is the skull and the spine itself made up of 26 movable vertebrae. These are the only structures encased in bone in the human body.
The nervous system can be separated very basically into two types of function. There is voluntary/somatic function, which controls what you consciously feel and motor activity such as conscious movement. There is also involuntary/autonomic function, which controls circulation, organ function, and immunity. Within this involuntary/autonomic portion of the nervous system, there is a sympathetic branch much like the on switch that gets you going when you get excited, an a parasympathetic branch like the off switch to calm things down when you relax.
Your brain controls all functions in your body by sending and receiving messages and chemicals though the nerves. When a vertebra, a single bone in the spine gets stuck or fixated in an improper position, it can affect the balance and/or flow within the nerves particular to that area of the spine. The resulting imbalance or change in the regulatory mechanism of the nervous system may lead to malfunction, dysfunction, and later dis-ease.
Dis-ease is actually a condition of malfunction of some type in the body for a period of time. What results are usually symptoms? If you treat the symptoms but don't remove the cause, you're not really correcting the problem. That's why Chiropractors work to restore proper function and balance to the nervous system. This is called homeostasis or good function and that is what results in good health!
