How many thoracic vertebrae are listed?

Explanation:
The chest region of the spine has twelve vertebrae, forming the middle portion between the neck and the lower back. These are labeled in order from top to bottom as the first through the twelfth thoracic vertebrae. This twelve-count aligns with the twelve pairs of ribs that attach to them, giving each thoracic vertebra its rib-articulation surfaces on the body and on the transverse process. So in a standard listing, you should see twelve thoracic vertebrae, reflecting the consistent division of the spine into seven cervical, twelve thoracic, and five lumbar vertebrae.
