The Upper Cervical Spine consists of two bones, the Atlas, (C1) and the Axis, (C2) at the top of the neck. Much of your nervous system passes through this vital area. This area is also the most movable area of your spine. Because of this, subluxations in this crucial area are very common.
Since this area is in such close proximity to the brain, subluxations here can result in an alteration to a large variety of body functions. Much of the body's nervous system messages flow past this point. This means that very large areas of the body are supplied by the nerves that pass through or near here.
Some of the areas of nerve supply that can be affected by subluxations in the upper cervical spine include your brain, head, and face. Nervous system interference here could result in headaches, facial palsy, sinus trouble, allergies, fatigue, cross-eyes, or dizziness.
In addition, if a pair of large and important nerves, the "Vagus" nerves, are affected by a subluxation in the upper cervical spine the parasympathetic nervous system function can be altered. These nerves are responsible for visceral motor function (control) of many of your chest organs as well as such functions as swallowing and your vocal cords.
Other areas that could experience functional changes that are controlled by the vagus nerve include such major organs as the heart, lungs, esophagus, stomach, gallbladder, and small intestines. As you can see, a subluxation affecting the vagus nerve can have a very wide and profound impact on the function and health of a large portion of your body.
