The side view X-ray must reveal three 63-degree arcs- 3 "C" Curves. The most important arc is in the neck (cervical spine) and should range between 34 and 43 degrees between C1 and C7 (the first and last cervical vertebrae). This cervical arc is known as the “Arc of Life” because mental life impulses travel directly from the brain down this part of the spinal cord to bring life to the rest of the body. Losing your Arc of Life causes the most severe obstruction to the brain, spinal cord and nerves, also known as the Central Nervous System (CNS)
If your CNS is unhealthy, you cannot become truly healthy by exercising or eating right alone. You can be healthier, but you cannot be at “normal” or optimal. Any “abnormal” position of the spine, misalignment of the bones, or any changes in these curves indicate a serious problem. It is absolutely vital to understand this point--any changes from “normal” will interfere with and eventually damage the Central Nervous System. Interference and damage to the Central Nervous System will always result in “abnormal” function of the body, improper healing, and poor, abnormal, or less than optimal health.

Normal Neck Curve
When bones of the spine lose their normal position or motion, sensitive nerves and blood vessels to the head can be affected. When spinal nerves and related tissues are stretched or irritated they can symptoms such as headaches and neck pain. Aspirin and medication may cover up these warning signs, but do not correct the underlying structural cause. Many patients with neck pain have lost the normal forward curve in the neck. Ultimately, this can affect the brain stem and spinal cord.
