The spine also called the backbone, is made up of vertebral bones with cushioning intervertebral discs between them. The spine is designed to give us stability and smooth movement, as well as providing a corridor of protection for the delicate spinal cord. It is supported by muscles, tendons, and ligaments, and innervated by nerves that branch out from the centrally placed spinal cord.
The thoracic spine is the central part of the spine, also called the dorsal spine, which runs from the base of the neck to the bottom of your rib cage. The thoracic spine provides the flexibility that holds the body upright and protects the organs of the chest. The spine is made up of 24 spinal bones, called vertebrae, of which, the thoracic region of the spine is made up of 12 vertebrae (T1-T12). The vertebrae are aligned on top of one another to form the spinal cord, which gives your body its posture. The different parts of the thoracic spine include bone and joints, nerves, connective tissues, muscles, and spinal segment.
