The spine consists of three vertebral columns, including the cervical vertebrae, lumbar vertebrae, and thoracic vertebrae. The cervical vertebrae are located in the neck. The lowest portion of the spine consists of the lumbar vertebrae. Between the cervical vertebrae and the lumbar vertebrae are the thoracic vertebrae. The 12 thoracic vertebrae are labeled T1 through T12, with T1 being closest to the skull and T12 being closest to the tailbone. Each vertebra is larger than the one above it, increasing in diameter as they run the length of the spine. The larger the segment, the more weight it is able to support. The seventh thoracic vertebra (T7) is located in the mid to lower dorsal area at the inferior angle of the scapula (shoulder blade).
