In a developing human being, the nervous system is the most important system. It is so important that it is the first system of the body to develop. The brain is the central command center, sending electrical signals or nerve impulses down the spinal cord to all regions of the body. The spinal cord and related nerves are a crucial communication link between the brain and the body and without them, normal function of the body would not exist.
The central nervous system is composed of the brain and the spinal cord which function almost like a command center, sending nervous impulses of information down to different levels of the spine. Here the spinal cord branches off into 31 pairs of spinal nerves on each side of the spine. These nerves combine with others and then branch out to the far reaches of the body.
There are 3 types of nerves: pain nerves, autonomic nerves and motor nerves. The most important and most common are the autonomic nerves and motor nerves. Autonomic nerves are under direct innate control and control your heart rate, your blood pressure, respiration, growth, immune function and digestion, to name just a few functions. Motor nerves control muscle function. Both the autonomic nerves and the motor nerves are so important to life that they make up over 90% of all nerves. The remaining nerves, 10% of the total, are the pain nerves. Unfortunately, pain nerves become active long after poor health has occurred. Pain is a very poor indicator of health as many conditions such as heart disease, cancer or even dental cavities can exist without pain.
Subluxations, or misalignment of the spinal bones, can cause interference of any of these nerves at the site where they exit the spine. Subluxations arise from stress and poor posture. Left unchecked, subluxations will eventually interrupt self-healing and self-regulating function, leading to poor health and disease.
