Where does the venous sinuses of the brain lie?
The venous sinus o fthe scalp are those of the superior sagittal sinus. TO read more about it check the meninges. The dural venous sinus is below the cranium, fibrous and serous dura and the endothelium
What drains venous blood from the brain and delivers it to the internal jugular veins?
The venous blood from the brain is drained by a network of veins called the cerebral venous sinuses. The largest of these sinuses is the superior sagittal sinus, which ultimately drains into the internal jugular veins.
What is the dural venous sinus that contains arachnoid granulations?
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
What are the arachnoid villi?
Arachnoid villi are small protrusions of the arachnoid mater (one of the meninges) that extend into the dural sinuses in the brain. They help to reabsorb cerebrospinal fluid (CSF) from the subarachnoid space back into the venous system, which helps to maintain proper intracranial pressure.
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 dural venous sinus that contains arachnoid granulations?
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
What veins drain blood from the brain?
The Internal Jugular drains the brain via the collection of blood from the superior sagittal sinus, inferior sagittal sinus, straight sinus, right transverse sinus, sigmoid sinus, and cavernous sinus (to name a few).....The other jugular....The External Jugular drains the occipital, facial (also drained by internal jugular), maxillary, and temporal veins.
What are the arachnoid villi?
Arachnoid villi are small protrusions of the arachnoid mater (one of the meninges) that extend into the dural sinuses in the brain. They help to reabsorb cerebrospinal fluid (CSF) from the subarachnoid space back into the venous system, which helps to maintain proper intracranial pressure.
Blockage of the scleral venous sinus might result in?
the correct answer is conjunctivitis
Venous channel between the two outermost meninges?
dural sinus
What is the most common name given to these venous sinuses?
Dural sinus
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 does the superior sagital sinus drain into?
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 returns venous blood from coronary system to right atrium?
Coronary sinus
What is the difference between a sinus and a vein?
A fistula is an abnormal pathway between 2 anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening.
