How Does It Work?
There are 7 neck (cervical) vertebrae, 12 mid back (thoracic) vertebrae and 5 lower back (lumbar) vertebrae, with a cartilaginous disc in between each vertebra. This disc is there to help cushion and absorb shock, reduce friction between the vertebrae and to allow increased movement to occur within the spine. A pair of spinal nerves exits between each vertebra. Each one of the 31 pairs of nerves comes from the spinal cord, which runs the length of the spine, and extends outwards to form a network which supplies and influences every organ, tissue and cell in the body.
It is a Chiropractors task to evaluate the biomechanical structure of the spine to ensure that each one of the individual vertebra are moving freely and are not displaced or fixed in any way.
Any such displacement or jammed vertebra can cause the spinal nerve that exits from the intervertebral foramen/opening, to become irritated either through direct pressure or through indirect stimulation/irritation.
Therefore any problem in any one of the vertebral joints can affect the related part of your nervous system, which in turn can lead to such symptoms as pain in the back or neck as well as many other health problems.
It is a Chiropractors task to evaluate and identify any problem that might exist within the spine and to correct any dysfunction that might be present
