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
They articulate with costal tubercles, with few exceptions
Facets are flat surfaces they correspond for this case the joining of the rib to the vertebra. They are detail part of the vertebra and the rib bones

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 fused articular processes
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!
- Transverse foramen (holes in the transverse processes through which travels the vertebral artery) - Uncinate processes (lip on the supero-lateral aspects of vertebral bodies)
There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.
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

Cervical vertebra - typical The cervical vertebrae contain foramina in the transverse processes, called foramina transversarium.
The thoracic vertebrae have 6 and all the others have 4.
transverse costal facets
Unlike all other thoracic vertebrae, 11th and 12th thoracic vertebrae lack articulation surfaces (for tubercle of ribs) on their transverse processes. The articulation facets (for head of rib) on the body of 11th and 12th thoracic vertebrae are large.
