 | | The cervical vertebrae are the seven vertebrae that form the upper part of your spine, between the skull and the chest. |
 | | The thoracic vertebrae are the 12 bones between your neck and your lower back. Thoracic vertebrae have cup-shaped surfaces called facets, in which the ribs rest and connect to the spine. These ‘joints’ help the ribs to move up and down during breathing. |
 | | Cervical arthritis tends to begin between the ages of 30 and 50 as part of the normal aging process; like all arthritic conditions, it may grow worse over time. Nearly everyone over the age of 50 experiences some wear and tear in the cervical spine, but not everyone develops symptoms of cervical arthritis. |
