A branch of the subclavian artery arises on either side of the body, and the vertebral arteries branch off and penetrate deep to the transverse process, usually at the level of the 6th cervical vertebrae (C6), or, in a small number of cases (7.5 percent), at the level of the 7th cervical vertebrae (C7). They then travel superiorly, through the transverse foramen of each cervical vertebra, until they reach the cervix.

What vessel travels through the cervical transverse foramen?
V2 (foraminal) is a vein that flows across vertebral veins and nerves in the spine. The vertebral artery enters a region between the vertebrae known as the transverse foramen at the C6 cervical vertebra and exits this area at the C2 cervical vertebra, which is the second-highest vertebra in your spine, just behind the head, at the top of your spine.
What passes through the transverse foramen of the cervical vertebrae?
The transverse foramen is a passageway that connects the vertebral artery and venous system to the vertebral body. It is placed medial to the tubercles of the transverse process and lateral to the spinal column.
Which artery goes through the transverse foramen?
It is an aperture that is occupied by the vertebral arteries and veins in the first six of the cervical vertebrae, and merely a vein in the seventh vertebrae, known as the transverse foramen (foramen transversarium) of the cervical vertebrae. In particular, the vertebral artery is significant because it provides blood flow to the brain and spinal cord.
Which vertebrae contains transverse foramen?
Vertebrae of the Cervical Spine In a normal cervical vertebra, the tiny body is surrounded by a bifid spinous process and transverse processes that each include a transverse foramen and are bent to allow for the transit of spinal nerves.
What goes through transverse foramen of c1?
The transverse process is a ring of bone that extends laterally from each lateral mass and is characterized by its uneven shape. Each transverse process is surrounded by a small transverse foramen, which is a hole in the neck that allows the vertebral artery and vein to pass through.
Where is the cervical area of the spine?
The cervical spine is made up of the first seven vertebrae of the spine, which are located at the top of the spine. It begins just below the level of the head and finishes just above the level of the thoracic spine. The cervical spine, like the lumbar spine, has a lordotic curvature (a backward C-shape), similar to the lumbar spine.
Do all cervical vertebrae have transverse foramen?
The presence of a single foramen in each transverse process is the most prominent feature of this process. They are encircled by the vertebral arteries and veins and are known as transverse foramina. This is true for all cervical vertebrae, with the exception of C7, whose transverse foramina contain only accessory veins and are thus not included.
Where is C1 and C2 on the spine?
The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine, and they are also known as the “twins.” The atlantoaxial joint, which is a pivot joint, is formed by the union of these two joints. The C1 is positioned on top and revolves around the C2 below it. The C1-C2 cervical joints are responsible for a greater proportion of the head’s rotational range of motion than any other cervical joint.
What transmits the vertebral artery and vein in the cervical vertebrae?
Additionally, the internal jugular and vertebral veins are located in front of the thoracic duct, and it is crossed by the inferior thyroid arterial branch; the left vertebral is also crossed by the thoracic duct. The transverse process of the seventh cervical vertebra, the sympathetic trunk, and the inferior cervical ganglion are all located behind the coccyx.
What foramen is present in cervical vertebrae but not in other vertebrae?
On all cervical vertebrae except the last, which has no transverse foramen, the vertebral artery travels through a hole in the side of the neck called the transverse foramen.
What is cervical vertebra?
When it comes to tetrapods, cervical vertebrae (plural: vertebra) refer to the vertebrae of the neck, which are located immediately behind the head.
Does C7 have transverse foramen?
In contrast to the other cervical vertebrae, the transverse foramen (bony hole) of C7 does not contain the vertebral artery (the artery that delivers blood to the brain), as does the foramen of C6. In rare circumstances, an additional cervical rib can develop from the seventh cervical rib.
What is the name of the first cervical vertebra?
Overview. The cervical spine is made up of seven bones, which are referred to as vertebrae. Atlas and axis are the names given to the first two C1 and C2 cells, which are highly specialized cells with distinct designations.
