Dural Venous Sinuses Consequently, an efficient system had to be established in order to allow blood to leave the restricted compartment. The venous drainage of the brain does not follow the arteries of the brain. Instead, they drain to the dural sinuses, which subsequently drain to the internal jugular vein. Generally, the walls of these drainage pathways are formed by visceral periosteum and dural reflection, both lined with endothelium.

Coronary sinus (June 2015) (Learn how and when to remove this template message) The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers deoxygenated blood to the right atrium, as do the superior and inferior vena cavae. It is present in all mammals, including humans. The name comes from the Latin corona' , meaning crown, since this vessel forms a partial circle around the heart.

- The left (2) and right (2) pulmonary veins drain oxygenated blood from the lungs into the left atrium. The oxygenated blood enters the left ventricle through a valve with two flaps, the left atrioventricular valve (mitral valve).

Straight sinus Straight sinus. The straight sinus, also known as tentorial sinus or the sinus rectus, is an area within the skull beneath the brain that receives venous blood. The straight sinus receives blood from the superior cerebellar veins and inferior sagittal sinus and drains into the confluence of sinuses.

Dura mater The two layers of dura mater run together throughout most of the skull. Where they separate, the gap between them is called a dural venous sinus. These sinuses drain blood and cerebrospinal fluid from the brain and empty into the internal jugular vein.

Dural Sinuses Veins draining the brainstem, cerebrum and cerebellum are like rivers that drain their contents into an estuary, the dural venous sinus. There are many of these found throughout the cranial cavity and the blood flowing through them eventually finds its way to the internal jugular vein and then on to the heart via the superior vena cava.

Midbrain & Pons Gross Anatomy Venous drainage of the midbrain and pons is achieved by both the vertebrobasilar veins and the venous sinus systems. Lateral and posterior mesencephalic veins drain the upper pons and the midbrain to the great cerebral vein of Galen, which drains to the confluence of sinuses by way of the straight sinus.

- The jugular veins are veins that bring deoxygenated blood from the head back to the heart via the superior vena cava.he internal jugular vein is formed by the anastomosis of blood from the sigmoid sinus of the dura mater and the common facial vein. The internal jugular runs with the common carotid artery and vagus nerve inside the carotid sheath.

Dural Venous Sinuses The cavernous sinus is the only one of the paired dural sinuses that communicates with each other. These sinuses have two intercavernous branches arching over the diaphragma sellae of the pituitary gland; one anterior and the other posterior to the infundibulum. They drain posteriorly by the petrosal sinuses.

Dural Sinus Thrombosis and Stroke A thrombosis is a blood clot. A dural sinus thrombosis is a blood clot inside of one of the dural sinuses. When a blood clot sits inside of one of the brain's sinuses, it causes a backup of blood inside the venous system of the brain, preventing blood from leaving the brain's tissues.

Paraganglioma The sigmoid sinus empties blood into a small cavity called the jugular bulb. From there, the blood enters a large vein in the neck called the internal jugular vein. The internal jugular vein then empties into larger blood vessels leading to the heart. The jugular bulb is located in the lower part of the middle ear.

- Function. While veins usually carry deoxygenated blood from tissues back to the heart, in this case, pulmonary veins are among the few veins that carry oxygenated blood instead. Oxygenated blood from the lungs is circulated back to the heart through the pulmonary veins that drain into the left atrium.mbryologically, the pulmonary arteries originate from the truncus arteriosus (as does the aorta), and in the developed heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle.

How to Freeze Split Pea Soup 1 Thaw bags of frozen split pea soup in the refrigerator overnight. 2  If your freezer space allows, you can use plastic containers to store your frozen split pea soup. 3  Only use containers that are labeled as being food-and freezer-safe.n addition, consuming split pea soup that you have prepared and frozen yourself can help you keep your sodium intake in check. A 1-cup serving of canned split pea soup may contain over 1,000 milligrams of sodium, while homemade soup can be prepared without any added salt and only a trace amount of sodium.

Jugular Vein Thrombosis Jugular Vein Thrombosis. The veins in the neck that drain blood from the brain, head, face and neck to the heart are known as jugular veins. External jugular veins drain blood from the skull and deep parts of the face, whereas internal jugular veins collect blood from brain, face and neck.

- The Vertebral Veins and Upright Posture. Vertebral Veins. The brain drains into two principle venous outlets. One route is the internal jugular veins. The other route is the vertebral venous systems. The openings to both drainage routes are located in the bottom of the posterior fossa of the cranial vault. The vertebral veins are actually part of a large network of veins called the vertebral venous plexus or VVP which is one aspect of the vertebral venous systems. The VVP is located alongside the spinal vertebra within the spinal canal.

Heart Anatomy The superior vena cava and inferior vena cava drain systemic venous blood into the posterior wall of the right atrium. The internal wall of the right atrium is composed of a smooth posterior portion (into which the vena cavae and coronary sinus drain) and a ridgelike, muscular anterior portion.

coronary vein one of the veins of the heart that drain blood from the capillary beds of the myocardium through the coronary sinus into the right atrium. A few small coronary veins that collect blood from a small area in the right ventricle drain directly into the right atrium. (1) Right coronary vein; vena coronaria dextra [NA6]. (2) Left coronary vein; vena coronaria sinistra [NA6]. (3) Left gastric vein; vena gastrica sinistra [NA6].

Dural venous sinuses The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood vessels. They differ from other blood vessels in that they lack a full set of vessel layers (e.g. tunica media) characteristic of arteries and veins.

Chapter 23: The pericardium and heart The venous drainage of the heart is (1) partly by small veins that empty directly into the cardiac chambers and (2) partly by veins that empty into the coronary sinus (fig. 23-9). The coronary sinus is a short, wide trunk that lies in the coronary groove between the left atrium and left ventricle.
