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 blood vessels travel through the transverse foramen?
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 goes through the transverse foramen?
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.
What blood vessels run through the transverse foramina of the cervical vertebrae?
The vertebral artery ascends via the transverse processes of the upper six cervical vertebrae and then descends into the aorta. The vertebral artery may be seen here. These holes in each vertebra allow the two vertebral arteries to flow through them.
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.
What does the ASA supply?
The anterior splanchnic artery (ASA) delivers blood flow to the anterior two-thirds to four-fifths of the spinal cord, which includes the anterior horn cells, anterolateral corticospinal and spinothalamic pathways, and the anterior horn cells of the brain (Barrow and Awad, 1999). The anterior white matter rim is additionally supplied by a pial radial plexus that arises from the ASA and branches out.
Which vessels supply the circle of Willis?
There are two arteries that feed blood to the brain, known as the carotid arteries. Those who follow them will be taken immediately to the circle of Willis, which is on either side of their neck. Each carotid artery is divided into two branches: the internal carotid artery and the external carotid artery. Later, the internal carotid artery divides into two branches, which are the cerebral arteries.
What goes through vertebral foramen?
The vertebral foramen is a passageway through which the spinal cord flows, which is surrounded by an arch. It is between the centrums that the cartilaginous intervertebral disks are located, which helps to soften the stress during locomotion.
What is atlas and axis?
The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are both a part of the seven cervical vertebrae, which are the most superior bones in the human body. Located directly behind the skull, the atlas is the top-most bone in the body, and it is followed by the axis. They work together to provide support for the head, allow for neck mobility, and protect the spinal cord.
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 structure goes through the vertebral foramen quizlet?
At C7, the transverse foramen (bony hole) is absent, unlike the other cervical vertebrae, which contains the vertebral artery (the artery that delivers blood to the brain). It is possible that from C7 an additional cervical rib will develop.
Where does the vertebral artery run through?
Located in the neck, the vertebral arteries provide blood to the brain and spinal cord as they travel along the spinal column. The vertebral arteries are a component of the circulatory system, which means they carry blood throughout the body. They are responsible for transporting blood to the brain and spinal cord, which are both components of the nervous system.
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 passes through the foramen magnum?
A huge oval aperture in the skull, known as the foramen magnum, through which the medulla oblongata travels, connecting the spinal cord to the brain.
Does C1 have vertebral foramen?
The vertebral foramen is the foramen (opening) produced by the anterior section (the body) and the posterior segment (the vertebral arch) of a typical vertebra. In the cervical spine, the vertebral foramen starts at cervical vertebra #1 (C1 or atlas) and extends inferiorly to lumbar vertebra #5. (L5).
