What is the venous drainage of the brain?
The deep system comprises of lateral sinus, straight sinus and sigmoid sinus along with draining deeper cortical veins. Both these systems mostly drain themselves into internal jugular veins. The veins draining the brain do not follow the same course as the arteries that supply it.
What veins drain the brain of blood and return to the heart?
jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava.
What vein drains blood from brain?
The two basal veins wind around the midbrainto drain blood into the great cerebral vein. Each of these veins is formed by the union of the anterior cerebral vein (a vena comitans), deep middle cerebral vein, and some inferior striate veins, and begins near the anterior perforated substance.
What is the main venous drainage of the heart?
Venous Supply to the Heart. The great cardiac vein, the middle cardiac vein, and the small cardiac vein all drain into the coronary sinus (which opens into the right atrium). The anterior cardiac veins drain directly into the right atrium.
Where does the venous drainage from the heart go?
The middle cardiac vein drains into the coronary sinus or directly into the right atrium [4]. The small cardiac vein, also known as the right cardiac vein [12], commonly drains the inferior and lateral wall of the right ventricle.
Where do veins drain?
Blood Supply and Lymphatics The veins in the upper extremity drain the deoxygenated blood. The drainage of blood allows for oxygenated blood to flow into the upper extremity. The veins do not perfuse the upper extremity with blood. The lymphatics of the upper extremity follows closely with the veins.
Which vein collects venous drainage?
To left of the left atrium, a string-like branch opens into the great cardiac vein, collecting the venous drainage from the area of the coronary fossa. This small venous branch wraps around the left coronary sinus, an area corresponding to the superior septal area.
What does the subclavian vein drain?
The primary function of the subclavian vein is to drain deoxygenated blood from the upper region of the body—including the arms and the shoulder areas—and transport it back to the heart. 6 Another important function of the subclavian is to collect lymph fluid from the lymphatic system from the internal jugular vein.
Who drains the blood from my head?
The blood vessel that drains blood from the head and upper extremities is the superior vena cava.
What is the major vein of the brain?
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 the largest vein that drains the heart?
The coronary sinus
The coronary sinus is the largest cardiac vein in terms of diameter. Various landmarks have been described as the location of the coronary sinus origin, including where the oblique vein of the left atrium meets the great cardiac vein and at the valve of Vieussens [4,7].
Is there any vein in brain?
These vessels are numerous and lie on the surface of the brain. The largest three are: the superficial middle cerebral vein lies over the Sylvian fissure, the vein of Trolard courses superiorly to the superior sagittal sinus, and the vein of Labbe drains into the transverse sinus.
What are the 3 major veins?
There are three major types of blood vessels: veins, arteries, and capillaries. Figure 7.4. 2: This figure shows the heart and the major arteries of the cardiovascular system. The pulmonary veins are included in the diagram because, like arteries, they carry oxygenated blood.
Which blood vessel is responsible for drainage of blood from heart?
Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers. Comprised of two venous systems, coronary veins classify into either the greater cardiac venous system or the smaller cardiac venous system.
What does the cephalic vein drain into?
The cephalic vein drains the radial part of the hand, forearm and arm and communicates along its course with the basilic vein, which drains the ulnar part. The cephalic vein empties directly into the axillary vein.
What does the axillary vein drain?
The axillary vein drains deoxygenated blood from the arm, axilla and superolateral chest wall 4. It also receives contributions from the thoracoepigastric vein of the anterolateral abdominal wall 5.
What is brain bleeding called?
Bleeding in the brain (also called a brain hemorrhage or brain bleed) can happen because of an accident, brain tumor, stroke, or high blood pressure caused by congenital or other health conditions. Brain bleed can reduce oxygen delivery to the brain, create extra pressure in the brain and kill brain cells.
What are the 4 main arteries supplying the brain?
The brain receives blood from two sources: the internal carotid arteries, which arise at the point in the neck where the common carotid arteries bifurcate, and the vertebral arteries (Figure 1.20). The internal carotid arteries branch to form two major cerebral arteries, the anterior and middle cerebral arteries.
What veins drain the brain?
Cerebral Veins. The cerebral veins drain the external surfaces and the internal regions of the cerebral hemisphere,respectively and are split into external (superficial) and internal cerebral veins.
What veins drain blood from the brain?
– Introduction. A blood clot in the veins that drain the blood from the brain is called a sinus or cerebral vein thrombosis. – Symptoms. – Diagnosis. – Treatment. – Recovery and Complications. – Further Resources. – Acknowledgments. – Footnotes.
What vein drains blood from the brain?
Overview. The veins of the brain are thin-walled,valveless and pierce the arachnoid mater and meningeal layer of dura mater (of meninges) to empty poorly oxygenated blood into the dural
What vein drains the dural sinuses of the brain?
Cavernous Sinus Thrombosis. Infection can spread from veins of the face into the cavernous sinuses,producing infection and thrombosis.
