The vertebral venous system plays an important role in the pathways of shoulder to ipsilateral posterior neck and shoulder to contralateral neck. Collateral pathways tend to develop in the intramuscular venous network in the poste- rior neck, and those veins reconstitute the vertebral vein (Fig. 10).
Where do the vertebral veins drain into?
Brachiocephalic veins Vertebral vein
| Drains from | Union of internal vertebral venous plexuses, a branch of occipital vein, veins of suboccipial and prevertebral muscles |
|---|---|
| Drains to | Brachiocephalic veins |
| Drainage area | Suboccipital muscles, prevertebral muscles, cervical spine |
What is Batson venous plexus?
Batson venous plexus, also known as Batson veins, are a network of paravertebral veins with no valves that connect thoracic vessels and deep pelvic veins draining the bladder, prostate, and rectum to the internal vertebral venous plexus 1.
What are venous plexuses?
A venous plexus is a congregation of multiple veins.
Is the vertebral vein in the neck?
This plexus ends in a single trunk, which emerges from the transverse foramina of the sixth cervical vertebra, and opens at the root of the neck into the back part of the innominate vein near its origin, its mouth being guarded by a pair of valves. …

What is vertebral vein system?
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.
How many vertebral veins are there?
the two vertebral arteries. the two vertebral veins. the anterior spinal artery. the two posterior spinal arteries.
What is the great cardiac vein?
The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.
What is femoral vein?
The femoral vein is the main deep vein of the thigh and accompanies the superficial femoral artery and common femoral artery.
Where does Batson plexus drain?
The Batson venous plexus (Batson veins) is a network of valveless veins in the human body that connect the deep pelvic veins and thoracic veins (draining the inferior end of the urinary bladder, breast and prostate) to the internal vertebral venous plexuses.
Where is the Batson plexus?
Batson’s plexus of veins is a complicated valveless network of veins located near the vertebral column. In normal conditions, it provides venous drainage of the brain and spine; in pathological conditions, it allows dissemination of infections and cancer.
Where is the venous plexus located?
The internal vertebral venous plexus is located beneath the bony elements of the vertebral foramina (laminae, spinous processes, pedicles, and vertebral body). It is embedded in a layer of loose areolar tissue know as the epidural (extradural) adipose tissue.
What is meant by Venae Comitantes?
Medical Definition of vena comitans : a vein accompanying an artery The accompaniment is so complete, in fact, that for much of the route up the arm, the vein network forms true venae comitantes, or parallel paired veins on either side of the artery.
What is portal circulation?
A portal circulation are connecting veins, which are an additional network of vessels between arterial and venous circulation. The veins between the connected capillaries are called portal veins.
What plexus drains bladder?
| Vesical venous plexus | |
|---|---|
| Drains from | Urinary bladder |
| Drains to | Internal iliac vein |
| Artery | Superior vesical artery Inferior vesical artery |

What vein is anterior to the vertebrae?
Anterior vertebral vein – Vena vertebralis anterior.
What is right subclavian vein?
The right subclavian vein is joined by the right lymphatic duct at the right venous angle, which drains lymph from the right upper quadrant of the body (right side of the head, neck, thorax, right upper extremity).
Where is the great cerebral vein?
The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum of the brain. It is also known as the vein of Galen, named for its discoverer, the Greek physician Galen.
What is vertebral column?
(ver-TEE-brul KAH-lum) The bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The vertebral column encloses the spinal cord and the fluid surrounding the spinal cord. Also called backbone, spinal column, and spine.
What are the vertebral arteries?
The vertebral arteries run through the spinal column in the neck to provide blood to the brain and spine. The vertebral arteries are part of the circulatory system. They carry blood to the brain and spinal cord, which are part of the nervous system.
What are spinal nerves?
Spinal nerves are the major nerves of the body. A total of 31 pairs of spinal nerves control motor, sensory, and other functions. These nerves are located at the cervical, thoracic, lumbar, sacral, and coccygeal levels.
Where is the brachial vein?
At this point, the brachial veins join the basilic vein to form the axillary vein. The brachial veins also have small tributaries that drain the muscles of the upper arm, such as biceps brachii muscle and triceps brachii muscle.
Is there a vein in the spine?
The spinal veins (veins of the medulla spinalis or veins of the spinal cord) are situated in the pia mater and form a minute, tortuous, venous plexus. They emerge chiefly from the median fissures of the medulla spinalis and are largest in the lumbar region.
What are cervical veins?
The deep cervical vein (posterior vertebral or posterior deep cervical vein) accompanies its artery between the Semispinales capitis and colli. It begins in the suboccipital region by communicating branches from the occipital vein and by small veins from the deep muscles at the back of the neck.
What are the three cardiac veins?
Coronary venous anatomy is highly variable, but is generally comprised of three groups: cardiac veins which drain into the coronary sinus: great cardiac vein. middle cardiac vein.
What is the largest cardiac vein?
Structure and Function
- The greater cardiac venous system returns three-quarters of the deoxygenated blood from the myocardium to the cardiac chambers. …
- The coronary sinus is the largest cardiac vein with multiple smaller vessels converging into it.
What is the vena cordis magna?
Anatomical terminology The great cardiac vein (left coronary vein) begins at the apex of the heart and ascends along the anterior longitudinal sulcus to the base of the ventricles. It then curves around the left margin of the heart to reach the posterior surface.
What is the function of the femoral vein?
A Large Paired Vein of the Thigh A large blood vessel of the thigh, the femoral vein is a major pathway in which blood from the lower limbs travels on its way back to the heart.
What does the femoral vein do?
Your tissues need blood to get oxygen and nutrients. Like other arteries in your body, the femoral artery carries oxygen-rich blood away from your heart. The femoral vein runs alongside the femoral artery. This vein carries deoxygenated blood from your lower body, back up to your heart.
Why is the femoral vein used?
The following are generally accepted indications for femoral venous catheter placement: Emergency venous access during cardiopulmonary resuscitation (CPR), in that it provides a rapid and reliable route for the administration of drugs to the central circulation of the patient in cardiac arrest.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
