What drains venous blood from the brain and delivers it to the internal jugular veins?
dural venous sinuses
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 cerebrospinal fluid in to venous blood in the dural sinus?
The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.
What is the dural venous sinus that contains arachnoid granulations?
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
What are cavities that filled with blood and help drain cerebrospinal fluid?
dural sinuses
What is found within the dural sinuses of the brain?
Venous blood
What is the common name given to the venous sinuses in the dura mater?
dural sinuses, cerebral sinuses, or cranial sinuses

dural venous sinuses
What is the most common name given to these venous sinuses?
Dural sinus
What do we call the fluid that is enclosed within the venous sinuses?
The fluid that is in the dural venous sinuses is venous blood that originates from the brain or cranial cavity. They collect blood from veins on the surface of the brain. Blood from the sinuses empties into the internal jugular veins
The dural sinuses are located in the?
dural folds
Are there any veins in body which are valveless?
Batson's venous plexus, Thebesian (smallest cardiac) veins in the myocardium, and Emissarry veins draining from Dural Venous sinuses are all valveless.

Where do the small veins of the brain empty into?
Dural Sinuses
Which of the three meningeal layers forms the dural venous sinuses?
The innermost membrane, the pia mater, consists mainly of small blood vessels and is the most vascular of the three meninges.
