to form a vertebral foramen in which the spinal cord (ad protected) is located and for attachment to posterior muscles such as erector spinae, trapezius, iliacus...
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.
- 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 simplest answer is because the 11th and 12th ribs (the last two) don't articulate with the transverse process of their corresponding vertebrae. Thus, transverse coastal facets are not needed.
The typical type of vertebrae containing foramina in the transverse process are cervical vertebrae. These foramina are called transverse foramina, and they allow for the passage of the vertebral artery and vein in the cervical spine.
You have such facets on thoracic vertebrae. They are there to hold the ribs.
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 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.

the transverse process and the articular process also spinous process
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.
Cervical vertebra - typical The cervical vertebrae contain foramina in the transverse processes, called foramina transversarium.
The simplest answer is because the 11th and 12th ribs (the last two) don't articulate with the transverse process of their corresponding vertebrae. Thus, transverse coastal facets are not needed.
The two lateral processes in the vertebrae are called the transverse processes. These bony projections extend laterally from the vertebral arch and serve as attachment points for muscles and ligaments, as well as articulation points for the ribs in the thoracic region.
The typical type of vertebrae containing foramina in the transverse process are cervical vertebrae. These foramina are called transverse foramina, and they allow for the passage of the vertebral artery and vein in the cervical spine.
At the thoracic vertebrae, joints include the intervertebral joints between the individual vertebrae, the costovertebral joints where the ribs articulate with the vertebrae, and the costotransverse joints where the ribs articulate with the transverse processes of the thoracic vertebrae.
