How many vertebrae are in the thoracic region?

Explanation:
The thoracic spine contains twelve vertebrae, labeled T1 through T12. This region aligns with the twelve pairs of ribs that articulate with the vertebrae, giving each thoracic vertebra a place to connect to a rib via costal facets on the body and, for ribs 1–10, on the transverse processes as well. The rib attachments, along with the orientation of the facet joints, make this part of the spine relatively stable and less mobile than the neck or lower back, which is well-suited to protecting the chest organs. Therefore, the standard count is twelve, not ten, eleven, or thirteen.
