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!)
Thoracic 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.
The surface that articulates with the ribs which is simply called the the "Demi-Facet" for the head of the rib. There is also a part on the transverse process of the thoracic vertebrae which acts as a block to prevent the rib from moving posteriorly.
Absolutely! They have features unique to the region they are found in, relating to structure and therefore function. Typical cervical vertebrae (C3-C6) usually have bifid spinous processes which point slightly inferiorly. The spinous processes on lumbar vertebrae are oblong in shape and point directly posteriorly. The articular facets of cervical vertebrae face superior-inferiorly, whereas lumbar articular facets face medial-laterally. Cervical vertebrae have transverse foramen on right and left(containing the vertebral arteries), lumbar have none. They have mamillary processes on their superior articular processes. The bodies of lumbar vertebra are larger and thicker than cervical vertebrae, though they are oval/kidney shaped shaped in both regions. The transverse processes of lumbar vertebrae are much longer, for muscle attachment. Cervical vertebrae have anterior and posterior tubercles extending from their transverse processes. The pedicles of lumbar vertebrae are slightly longer and more defined than those of cervical vertebrae. I think that covers everything, let me know if you think of anything else!
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).
- Transverse foramen (holes in the transverse processes through which travels the vertebral artery) - Uncinate processes (lip on the supero-lateral aspects of vertebral bodies)
You have such facets on thoracic vertebrae. They are there to hold the ribs.
the transverse process and the articular process also spinous process
Cervical Vertebrae- has transverse foramen, and a bifid tip of spinous process Thoracic Vertebrae- Has coastal facets on the sides of the body Lumar Vertebrae- has no transverse foramen, no bifurcated tip, and no facets on the sides of the body

The two lateral processes in a vertebrae are called transverse processes. Their main function is to provide attachment points for muscles and ligaments that help stabilize and move the spine.
They originate from the transverse processes from the cervical vertebrae of C2 to C7 and insert onto the first and second ribs. Thus they are called the lateral vertebral muscles.
- Transverse foramen (holes in the transverse processes through which travels the vertebral artery) - Uncinate processes (lip on the supero-lateral aspects of vertebral bodies)
Transverse foramina are small openings within the transverse processes of the cervical vertebrae. These foramina allow the passage of the vertebral artery and vertebral veins, which supply blood to the spinal cord and brain.
The vertebrae that contain a transverse foramen, bifid spine, and small body is the cervical vertebrae. The seventh cervical vertebra (C7), also known as the vertebra prominens, typically has these characteristics.
