The superior sagittal sinus is an area above/behind the brain, which allows blood veins to span the area, from the top of the head towards the back. It is believed that the CSF drains through the arachnoid villi into the dural venous sinuses of the superior sagittal sinus. The CSF then drains into the internal jugular veins.

What is the protective covering of the brain that provides passageways for cerebrospinal fluid to drain into the superior sagittal sinus?
The protective covering of the brain that provides passageways for cerebrospinal fluid to drain into the superior sagittal sinus is the arachnoid mater. This membrane is located between the dura mater and the pia mater and helps regulate the flow of cerebrospinal fluid in the brain.
What is a vein in the dura mater roughly parallel to the longitudinal fissure?
The superior sagittal sinus is a vein located in the dura mater that runs parallel to the longitudinal fissure of the brain. It collects blood and cerebrospinal fluid from the superior aspects of the brain and drains into the internal jugular vein.
What drains blood from the myocardium to the right atrium?
The coronary sinus is the main vessel that drains oxygen-depleted blood from the myocardium into the right atrium. It collects blood from the cardiac veins that run throughout the heart muscle and then empties into the right atrium of the heart.
What is Dura Mater?
Dura matter is tough outer coat on the brain. Inside it you have arachinoid matter. Innermost is pia matter. Outer coat of dura matter goes along with the inner layer of skull. Inner layer goes with the folds of brain. So you have falx cerebri. Above of which you have superior sagittal sinus and below is inferior sagittal sinus. Superior sagittal sinus is between outer and inner dura matter and inferior sagittal sinus is fold of inner layer of dura matter only. Then you have tentorium cerebelli and falx cerebeli. So you have cavernous sinus, superior and inferior petrosal sinus. Transverse sinus and sigmoid sinus Draing into internal jugular vein, through jugular foramen. ( Along with 9,10 and 11th cranial nerve.) Then straight sinus at the inferior border of falx cebri, posteriorly. And sinus coming from cerebellum below. This tough fold protects the delicate brain by forming compartments in it. It also helps in flow of venous blood, by forming venous sinuses.

What is the protective covering of the brain that provides passageways for cerebrospinal fluid to drain into the superior sagittal sinus?
The protective covering of the brain that provides passageways for cerebrospinal fluid to drain into the superior sagittal sinus is the arachnoid mater. This membrane is located between the dura mater and the pia mater and helps regulate the flow of cerebrospinal fluid in the brain.
What are the three blood vessels that drain into the right atrium?
As far as know they are the Coronary Sinus, the Superior Vena Cava and the Inferior Vena Cava.
Which air sinus opens in superior nasal meatus?
The frontal sinus opens in the superior nasal meatus.
What venous sinus extends from the superior cistern to the confluence of the sinuses?
The superior sagittal sinus extends from the superior cistern to the confluence of sinuses. It is located within the superior margin of the falx cerebri and drains blood from the majority of the cerebral hemisphere.
What is the venous sinus that overlies the brain superiorly?
The superior sagittal sinus overlies the brain superiorly and runs within the falx cerebri. It drains blood from the superior aspects of the brain towards the confluence of sinuses.
What is the dural venous sinus that contains arachnoid granulations?
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
What blood vessels drain blood into the rigth atrium?
Coronary sinus, in turn empties into the right atrium Coronary sinus, in turn empties into the right atrium Coronary sinus, in turn empties into the right atrium Coronary sinus, in turn empties into the right atrium
Which chamber does the coronary sinus drain into?
The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the myocardium of the heart. It is present in humans and other animals. It delivers deoxygenated blood to the Right atrium in conjunction with the superior and inferior vena cava.Wikipedia
Superior vena cava and coronary sinus originate where?
The heart.
Into which heart chamber does the coronary sinus drain?
The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the myocardium of the heart. It is present in humans and other animals. It delivers deoxygenated blood to the Right atrium in conjunction with the superior and inferior vena cava.Wikipedia
The great and middle cardiac veins drain blood into the?
The great and middle cardiac veins drain blood into coronary sinus. The coronary sinus is responsible for draining blood from the anterior ventricles.
