The thoracic vertebrae are a group of twelve vertebrae located in the middle part of the vertebral column. Here are key details about the thoracic vertebrae:


The thoracic vertebrae are situated between the cervical vertebrae (which are in the neck) and the lumbar vertebrae (which are in the lower back).

They are labelled T1 to T12, starting from the top near the base of the neck and extending down to the upper lumbar region.


  • Vertebral Body: The vertebral bodies of the thoracic vertebrae are larger than those of the cervical vertebrae but smaller than the lumbar vertebrae. They are somewhat heart-shaped.
  • Vertebral Arch: Each thoracic vertebra has a vertebral arch that encloses and protects the spinal cord.
  • Spinous Process: The spinous processes of thoracic vertebrae are long and pointed downward, overlapping the next vertebra below, which helps provide stability to the thoracic spine.
  • Transverse Processes: These extend laterally from the vertebra and serve as attachment points for muscles and ligaments.
  • Articular Processes: The superior and inferior articular processes form joints with adjacent vertebrae, allowing for some movement and flexibility.
  • Costal Facets: Unique to the thoracic vertebrae, these facets on the vertebral bodies and transverse processes articulate with the ribs, forming the rib cage.


  • Support: The thoracic vertebrae support the upper body and provide attachment points for the ribs and muscles of the back.
  • Protection: They protect the spinal cord, which runs through the vertebral foramen (the central opening in each vertebra).
  • Movement: The thoracic spine allows for a range of movements, including rotation and some degree of flexion and extension, though it is less mobile than the cervical and lumbar regions due to the rib cage’s stabilizing effect.

Clinical Significance:

  • Injuries: The thoracic vertebrae can be subject to fractures or dislocations due to trauma, such as falls or car accidents. Such injuries can affect the spinal cord and lead to serious neurological consequences.
  • Degenerative Conditions: Conditions like osteoarthritis, degenerative disc disease, or herniated discs can affect the thoracic spine, causing pain, stiffness, and other symptoms.
  • Scoliosis: This is a condition where there is an abnormal lateral curvature of the spine, often involving the thoracic region. It can lead to asymmetry in the rib cage and posture.

The thoracic vertebrae play a crucial role in the structure and function of the vertebral column, providing support and protection while allowing for movement and flexibility.
