How many thoracic vertebrae are there?

Explanation:
There are twelve thoracic vertebrae in the standard human spine, labeled T1 through T12. This region sits between the cervical (neck) and lumbar (lower back) sections and aligns with the twelve pairs of ribs that attach to it. The sequence of vertebral regions is seven cervical, twelve thoracic, five lumbar, then sacral and coccygeal segments (fused). Because the thoracic region is defined by its rib articulations, its typical count is 12, making that option the correct one.
