APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The thoracic region contains 12 vertebrae, denoted T1-T12. The intervertebral discs, along with the laminae, pedicles, and articular processes of adjacent vertebrae, create a space through which spinal nerves exit.

Detailed explanation-2: -Thoracic vertebrae (Fig. 2) form the midline of the posterior wall of the thoracic cavity. There are 12 thoracic vertebrae; corresponding to 12 pairs of ribs (Oostra et al.

Detailed explanation-3: -Seven bones in the neck-the cervical spine. 12 bones in the chest-the thoracic spine. Five bones in the lower back-the lumbar spine.

Detailed explanation-4: -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-5: -The eleventh thoracic vertebra (T-11) has an intact, superiorly placed costal facet on each side of the vertebral body but no costal articulation on the transverse processes. The twelfth thoracic vertebra (T-12) resembles T-11, but the inferior articular facets assume the lumbar pattern.
