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.
Is blood drained from brain by a set of dural sinuses?
Yes. Fibrous - Serous dura matter - endothelium - dura venous sinus - endothelium - serous - arachnoid matter ....so then the answer is really No, it is between the 2 layers of the dura.
What is a vein in the dura mater roughly parallel to the longitudinal fissure?
fissure vein dural venous sinus
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.
Where are Dural venous sinuses found?
Dural venous sinuses are formed in areas where the two layers of the dura mater separate, forming spaces
What is the common name given to the venous sinuses in the dura mater?
dural sinuses, cerebral sinuses, or cranial sinuses
What is found within the dural sinuses of the brain?
Venous blood
What drains venous blood from the brain and delivers it to the internal jugular veins?

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?

What is the dural venous sinus that contains arachnoid granulations?
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
Where do the small veins of the brain empty into?
