While chiropractic is not involved with the chasing of symptoms per se, it is essential to understand the neurological basis for many health complaints. Towards that end, we have compiled reference materials to assist in your understanding of how the nervous system controls and coordinates all functions in the human body.
Where Is 4C Located?
The fourth spinal vertebra under the skull is called the fourth cervical. There are seven cervical vertebrae all together, and we will consider them one at a time.
Where Do The Nerves Go?
4C, according to our Neuro-Anatomy chart, is involved with providing the primary nerve supply from the control centers in the brain to the thyroid, mucous membranes, lung, and mouth. While the direct neurological connection has not been established in the literature, it is commonly found to be a subluxated area (misaligned producing abnormal nerve system transmission of information). Nerve interference at this level leads to such common health complaints as either Hypothyroid (reduced function), causing weight gain and feeling cold. Or Hyperthyroid (overactive), causing insomnia nervousness and weight loss.
What Are Causes 4C Subluxation?
4C subluxation can be caused by physical, chemical, emotional and/or environmental stress or a combination of these stressors beyond the body’s ability to cope. These stressors can not only cause C4 subluxation, but many of the following stressors may also be effects of this subluxation. Everyday stressors affecting this part of the spine and nervous system include anxiety, irritability, nervousness, insomnia, fatigue, irregular heartbeat, confusion, depression, and breathing difficulties.
Local effects vs. Global effects
We know that the adverse local effects of the subluxation are harmful enough, but the impact on the whole body is even more critical. Subulaxtion of 4C could affect the thyroid, heart, hearing, temperature regulation, overall energy level, and mental state.
As you can see, the nervous system isn’t merely a this for that approach to health. Everything is inter-related, and your chiropractor’s expertise is in determining the causes of BOTH health problems and health itself.
