The thoracic spine consists of which vertebrae?

Explanation:
The thoracic spine is the mid-back section that includes twelve vertebrae, labeled from T1 to T12, located in the chest area and forming the posterior part of the rib cage. This region is distinct from others: the cervical spine in the neck, the lumbar spine in the lower back, the sacrum which is a fused block at the base of the pelvis, and the coccyx or tailbone at the very end. A key feature of the thoracic vertebrae is their articulation with the ribs, which reinforces why they sit in the chest region. Thus, the thoracic spine comprises those twelve T1–T12 vertebrae in the chest.
