The Thoracic Vertebrae have such features and are in the correct position to articulate with the ribs correctly (the cervical vertebra are too high to touch the ribs in the neck region, and the lumbar, sacral and coccyx are all too low to intersect the ribs!)

A special feature present on the transverse process of cervical vertebrae?
The transverse processes of the cervical vertebrae are pierced by a "foramen transversarium" through which the vertebral artery passes. The transverse processes of the cervical vertebrae are pierced by a "foramen transversarium" through which the vertebral artery passes.
What articular surfaces are unique to the thoracic vertebra?
The thoracic vertebrae have facets on their transverse processes for articulating with the ribs, which are unique to them. Additionally, they have demi-facets on their bodies for articulating with the heads of the ribs, making them distinct from the cervical and lumbar vertebrae.
How many cervical thoracic and lumbar vertebrae are there?
There are 7 cervical vertebrae in the neck, 12 thoracic vertebrae in the mid-back, and 5 lumbar vertebrae in the lower back. In total, there are 24 vertebrae between the cervical, thoracic, and lumbar regions of the spine.
What are the parts of the vertebrae and how many bones are located in each selection?
The vertebrae consist of the vertebral body, spinous process, transverse process, and articular processes. There are 33 vertebrae in total, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
Cervical vertebrae can be distinguished from other types by the?
presence of transverse foramina in the transverse processes, through which the vertebral artery passes to supply blood to the brain.
