Nerve Root Levels & The Body Part Affected

Posted on December 1, 2014 at 8:15 PM

There are 31 pairs of nerve roots which stem out from your spinal cord to the different organs and tissues of the body. The area of the spinal column from which they exit is called the intervertebral foramina. When the segments of the spine are out of alignment or “subluxated”, the spacing of the intervertebral foramina is decreased and thus places pressure on the nerve roots. When this happens, the specific nerve root(s) being affected will cause specific organs and tissues of the body to malfunction, as they are unable to receive the full functioning information from the brain. The continued pressure on the nerve roots and lack of information from the brain will cause the organs and tissues to malfunction, which in turn contributes to if not creates the many ailments and illnesses you may be feeling. It is also important to note that you have the vertebral artery running through the transverse processes of the cervical vertebra. Subluxations in the neck are not only pinching on the nerve roots, but decreasing the flow of blood to your brain – think about that one for a while.

 

Below is a breakdown of the nerve roots and the areas of the body they specifically affect. The nervous system is complex. Only the most significant relationships are shown below. Many organs and tissues have multiple nerve supplies. As the brain and spinal cord are a homologous system, meaning it is one system, there are times when certain areas of the body may have an issue and it is not related to the specific nerve root, but a malfunctioning of the nervous system as a whole – that is why when I treat you, I check you from head to toe, not just the areas you may have a complaint about. Most of you know that you may not always have a complaint/issue when you come in for your scheduled follow-ups. This has to do with the cellular activation and action potentials in your nerve cells. As you get healthier and do your home stretching and strengthening, the less frequent you have to come in.
