The human body is a self-contained, self-governing and self-protecting vehicle which is designed to “live” many years. The body, with its framework of bones, its moving parts and motors of muscles and organs and its communication system of nerves, is controlled by the rational and sentient capacity of the brain. With all the parts functioning smoothly life is known, experienced and enjoyed.
The nerves can be traced back to a point where they leave the backbone and enter the spinal column through small bone sections called vertebrae. These separate sections are bound together into a strong, flexible vertebral column by muscles and fibers. Between these sections or segments are protective cushions of cartilage.
