The spine has a total of 24 individual bones, called vertebrae, running from the head down to the pelvis. Each bone is separated from the next by a disc, the purpose of which is to allow movement and act as a shock absorber. The main purpose of the spine is to provide protection to the spinal nerves which control the majority of the body.
The neck consists of seven bones, or vertebrae. These are shaped to allow a tremendous amount of flexibility of head movement which is critical to allow the eyes and ears to follow subjects.
The nerves which exit the spinal canal in the neck are responsible for the head shoulders and arms. Problems such as headaches, loss of neck movement and pain in the neck, plus pain, pins and needles, numbness and loss of strength in the arms, can all result from nerve irritation in the neck.
