ANATOMY

Detailed explanation-1: -Your thoracic spine consists of 12 vertebrae numbered T1 to T12. Each number corresponds with the nerves in that section of your spinal cord, as well. These nerves branch off of your spinal cord and supply sensation (feeling) and movement to certain areas of your body.

Detailed explanation-2: -The twelve thoracic vertebrae are strong bones that are located in the middle of the vertebral column, sandwhiched between the cervical ones above and the lumbar vertebrae below. Like typical vertebrae, they are separated by intervertebral discs.

Detailed explanation-3: -The thoracic cage (rib cage) forms the thorax (chest) portion of the body. It consists of the 12 pairs of ribs with their costal cartilages and the sternum (Figure 7.5. 1). The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1–T12).

Detailed explanation-4: -Thoracic (middle back): The chest or thoracic part of the spine has 12 vertebrae (T1 to T12).

Detailed explanation-5: -The primary characteristic of the thoracic vertebrae is the presence of costal facets. There are six facets per thoracic vertebrae: two on the transverse processes and four demifacets-the facets of the transverse processes articulate with the tubercle of the associated rib.
