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 holes in the transverse processes of cervical vertebrae are called transverse foramina. These foramina are unique to the cervical vertebrae and allow for the passage of the vertebral arteries and veins, which supply blood to the brain. They play a crucial role in the vascular system of the head and neck.
Cervical vertebra - typical The cervical vertebrae contain foramina in the transverse processes, called foramina transversarium.
Cervical Vertebra - Typical
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)
The transverse processes of the first cervical vertebra (C1) are also known as the lateral masses. They are prominent bony structures that extend laterally from the sides of the vertebra and serve as points of attachment for muscles and ligaments.
Cervical vertebrae can be identified by their distinct features: they are smaller and have a unique structure with transverse foramina in the transverse processes, which allow for the passage of vertebral arteries. The first two cervical vertebrae, the atlas (C1) and axis (C2), have specialized shapes that enable pivotal head movements. Additionally, cervical vertebrae typically have a bifid spinous process, except for C7, which has a longer, non-bifid spinous process.
The foramen present in cervical vertebrae that is not found in other vertebrae is the transverse foramen. This foramen allows for the passage of the vertebral arteries and veins, which supply blood to the brain. It is a distinguishing feature of cervical vertebrae, specifically located in the transverse processes.
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.
Transverse foramina (on all cervical vertebrae) and bifid spinous process on C2-C6
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.
