What is vertebral vein?
The vertebral vein is a paired vessel found in the transverse foramina of the cervical vertebrae on either side of the neck. The function of the vertebral vein is to drain the venous blood from the cervical spine, prevertebral and suboccipital muscles.
Is there a vertebral vein?
The vertebral vein. (Vertebral labeled at upper left and center right.) The vertebral vein is formed in the suboccipital triangle, from numerous small tributaries which spring from the internal vertebral venous plexuses and issue from the vertebral canal above the posterior arch of the atlas.
How many vertebral veins are there?
the two vertebral arteries. the two vertebral veins. the anterior spinal artery. the two posterior spinal arteries.
What does the vertebral vein supply?
The vertebral blood supply for the spinal cord comes from many different sources in the body depending on the region. The main blood supply to the spinal cord is via the single anterior spinal artery (ASA) and the two posterior spinal arteries (PSA).
Where is the brachial vein?
The brachial artery and vein can be found by palpating the medial intermuscular septum in the proximal and middle thirds of the arm. The vein is medial and posterior to the artery in this area.
Where is left vertebral artery?
neck
The left subclavian arises directly from the aorta. The vertebral arteries run separately inside the left and right sides of the spinal column in the neck. The suboccipital muscles at the base of the skull cover the vertebral arteries. This area is the suboccipital triangle.
Is there a right and left vertebral vein?
Right and left longitudinal prevertebral veins (stars) are located medially to musculus longissimus colli (L) and in front of cervical vertebrae.
What are vertebral venous plexuses?
The vertebral venous plexus is a highly anastomotic network of valveless veins running along the entire length of the vertebral column from the foramen magnum to the sacral hiatus.
What is the anatomy of the spinal cord?
The spinal cord is a cylindrical structure of nervous tissue composed of white and gray matter, is uniformly organized and is divided into four regions: cervical (C), thoracic (T), lumbar (L) and sacral (S), (Figure 3.1), each of which is comprised of several segments.
What is a radial vein?
Medical Definition of radial vein : any of several deep veins of the forearm that accompany the radial artery and unite at the elbow with the ulnar veins to form the brachial veins.
Which arm veins are deep?
Deep veins — The deep veins of the upper extremity include the paired ulnar, radial, and interosseous veins in the forearm; paired brachial veins of the upper arm; and axillary vein. The axillary vein becomes the subclavian vein at the lower border of the teres major muscle (figure 2).
Where does the vertebral vein form in the body?
The vertebral vein (Latin: vena vertebralis) is a venous blood vessel that is formed by numerous small tributaries arising from the internal vertebral plexuses. The vertebral vein arises from the external venous plexus at the level of the posterior arch of the atlas (C1). The vein accompanies the vertebral artery, forming a plexus around it.
Where are the veins of the neck located?
They unite with small veins from the deep muscles at the upper part of the back of the neck, and form a vessel which enters the foramen in the transverse process of the atlas, and descends, forming a dense plexus around the vertebral artery, in the canal formed by the foramina transversaria of the cervical vertebrae .
Where does blood go after leaving the vertebral column?
Highlights. After receiving blood from the region of the vertebral column, the internal venous plexus drains into the external venous plexus via the intervertebral veins. In turn, the external one drains into the vertebral veins of the neck and the segmental veins of the trunk.
Where does the venous plexus begin and end?
For the sake of clarity, we should emphasize that this venous plexus arises within the suboccipital triangle and traverses the transverse foramina up to the C6 level, after which it is continued by a single vertebral vein on each side of the neck.
