In Depth: Upper Back. The spine in the upper back and abdomen is known as the thoracic spine. It is one of the three major sections of the spinal column. The thoracic spine sits between the cervical spine in the neck and the lumbar spine in the lower back. Collectively, these three sections make a tower of 24 bones that gives the body structure and houses the spinal cord. The spinal cord and its nerves facilitate communication between the body and the brain.
