Explanation: 

Detailed explanation-1: -Your thoracic spine consists of 12 vertebrae, labeled T1 through T12. Vertebrae are the 33 individual, interlocking bones that form your spinal column. These bones help protect your spinal cord from injury while allowing you to twist and turn.

Detailed explanation-2: -There are 12 pairs of spinal nerves that originate from the thoracic segments of the spinal cord. These nerves mainly supply the skin over the chest and intrinsic back muscles of the thoracolumbar region. The thoracic nerves also supply some of the areas of skin over the abdomen and axilla.

Detailed explanation-3: -In humans, the vertebral column usually consists of 33 vertebrae, placed in series and connected by ligaments and intervertebral discs. However, the number of vertebrae can vary between 32 and 35. Usually there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 caudal (coccygeal) vertebrae.
