How many thoracic vertebrae are listed?

Explanation:
The thoracic region contains twelve vertebrae, labeled T1 through T12. This twelve-vertebrae count is standard for the thoracic spine and aligns with the rib attachments, as each thoracic vertebra typically articulates with a pair of ribs. The other numbers refer to other parts of the spine or total counts: seven are in the cervical region, five are in the lumbar region, and 33 is a total vertebrae count sometimes used when including fused sacral and coccygeal segments. So, twelve is the correct count for thoracic vertebrae.
