What is a thoracic?

The thoracic spine is located in the upper and middle part of the back. Twelve vertebrae are located in the thoracic spine and are numbered T-1 to T-12. Each number corresponds with the nerves in that section of the spinal cord: T-1 through T-5 nerves affect muscles, upper chest, mid-back and abdominal muscles.

The thorax is also called the chest and contains the main organs of respiration and circulation. The heart through its main artery, the aorta, pumps oxygenated blood to all parts of the body.

The inferior thoracic aperture is almost completely covered by the diaphragm, separating it from the abdominal cavity.
