Nerve Chart

Your Spine and Nervous System:

Your nervous system controls and coordinates every function of your body. It is your nervous system that allows you to adapt to, and live in your environment. A large portion of your nervous system passes through your spine. It is your spinal cord that acts as the major cable exiting your brain, travels down inside your spinal column and branches off into spinal nerves at various levels of your spine. These spinal nerves then exit between individual spinal vertebrae and go to the various parts of your body. To be healthy it is essential that your nervous system function properly and free from any interference caused by subluxations. Subluxations can cause interference to the nervous system at any point along the spine where the nerves exit. This can adversely affect the function of various parts of your body, and ultimately your health.


The chart below is designed to give you a look at just some of the relationships between the areas of your spine and your nervous system. Keep in mind that your nervous system is much more complex than can be shown here.

Upper Neck


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.

Mid & Lower Neck


The cervical spine consists of seven vertebrae. Shown here are the third cervical, (C3) through the seventh cervical, (C7) vertebrae. When the nerves that pass through this area are involved with subluxation areas such as the neck muscles, the shoulder, as well as the arms and hands are affected. In these situations, problems such as neck pain, arm pain, numbness, stiff neck, bursitis, as well as many other musculoskeletal problems are possible.
In addition to these areas, nerves originating in this area of the spine innervate the throat, sinuses, nose, thyroid gland, lymph nodes, diaphragm, and other organs and systems. When subluxation is involved in these areas a variety of functional problems can result.
It is imperative for the organs, systems, muscles, joints and all other tissues in these areas to receive proper nerve signals in order for them to function as they were intended. Subluxation reduces this function thus allowing the areas supplied by the nerves to be working at less than their optimal ability. As with any portion of the spine, subluxations in this area can also have an effect on other segments of the spine and creating imbalances, postural problems, and functional problems elsewhere.

Mid Back


The thoracic spine, commonly referred to as your middle back, consists of 12 vertebra (T1-T12). This is the longest portion of your back.
Each of these vertebrae has a pair of ribs attached to them. The nerves that exit out between these vertebra go to muscles and other surface tissues as well as internal organs.
Some of the surface areas these nerves go to include parts of the arms from the elbows down, the hands, and fingers. Also the muscles of the middle back, the chest muscles, and muscles of the rib cage are supplied by nerves that exit out from this area of the spine. Pain or numbness and other musculoskeletal problems may be just some of the possible results from subluxations affecting these areas and tissues.
The internal organs supplied by nerves from the thoracic spine include much of the body parts supplied by the sympathetic nervous system. This portion of the nervous system innervates many of the organs in the chest and abdomen including, the heart, lungs, bronchial tubes, gallbladder, liver, stomach, pancreas, spleen, adrenal glands, kidneys, and small intestines. Subluxations affecting these organs can lead to a large list of functional and systemic problems including, asthma, certain heart problems, bronchitis, blood pressure problems, ulcers, allergies, kidney trouble, and digestive problems, to name only a few. Most subluxations affecting these areas go undetected for a long time before a health problem is ever noticed.

Lower Back


The Lumbar Spine is the part of your spine commonly referred to as your “lower back”. It consists of five large vertebrae, (L1 – L5). Although this is an area of the spine that many people recognize when they think of pain, the nerves that exit this portion of the spine have responsibilities for vital body functions. This area of your spine has the largest and strongest vertebrae and some of the largest muscles supporting it.
The nerves that exit from these areas are large and control some very large muscles. These muscles include the large and small muscles of the lower back, the muscles of the thigh, legs, calf muscles, and feet. The sciatic nerve has its origin from the nerves that exit from the lumbar spine. In addition to the muscles, many joints in this area are also supplied by nerves from the lumbar spine including the hips, knees, ankles and feet.

Many organs and tissues also get their nerve supply from nerves that exit from the lumbar spine. These include the large intestines, appendix, male or female reproductive organs, the bladder, prostate gland, and others. Subluxations in these areas can have a vast affect including pain in the lower back, legs, or sciatic pain. Numbness in the back and legs is also possible. Muscle spasm or weakness can also result. Scoliosis and joint problems are also possible. If the organs supplied by these nerves are affected, the possible results include, constipation, diarrhea, cramps, varicose veins, bladder problems, menstrual problems, infertility problems, bed wetting, urination problems, and poor circulation, among others.



The sacrum and coccyx are commonly referred to as your “base bone” or “tail bone”. As a child the sacrum consists of five individual bones and the coccyx is made up of three to five bones. In the adult, the sacral segments and the coccygeal segments fuse so that each of these two bones are solid singular bones. The sacrum forms joints with each of the hip bones and helps to stabilize the pelvis. The nerves that exit the sacrum and coccyx go to the tissues and organs in that area. These include the muscles of the buttocks and hips as well as portions of the thigh and leg.

In addition, organs and tissues such as the rectum and portions of pelvic tissues are also innervated by these nerves. As a result, some of the problems that may occur as a result of subluxations here could be sacroiliac conditions, hemorrhoids, scoliosis, and pain when sitting.
