What function reabsorbs cerebral spinal fluid back into the blood?
arachnoid granulations Normally the pressure of the CSF is higher than that of the venous system, so CSF flows through the arachnoid villi and granulations into the blood
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 subarachnoid space?
The space between the arachnoid and pia mater is called the subarachnoid space
What is contained between the archnoid and pia layers of the membrane of the brain?
Deep to the arachnoid layer of the meninges is the pia mater.
Where is the sub-arachnoid space?
There is normally an actual space between the arachnoid layer and the pia mater known as the subarachnoid space. As noted, it contains many fibrous filaments, known as trabeculae (little beams), joining and stabilizing the two layers
What is the space between the pia mater and the arachnoid membrane called?

What is sub brachia hemorrhage?
I think you are referring to "sub-arachnoid hemorrhage". This is a type of brain hemorrhage occurring underneath the arachnoid membrane which envelopes the brain and can be caused by bleedding from an aneurysm
The subarachnoid space lies between what two layers of meninges?
pia and arachnoid
