How does the neck work?
The 7 bones that form the neck are called the cervical vertebrae. They're linked together by facet joints which, together with the neck muscles, allow you to move your head in any direction. Between the bones are discs of cartilage known as intervertebral discs. At the level of each disc, nerve roots branch out from the spinal cord. Impulses travel along these nerves, sending sensations such as touch and pain to the brain. The bones help to support the head and protect the spinal cord – the main nerve which links nerves throughout the body to the brain.
