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
Where does Cerebrospinal fluid enter the bloodstream?
arachnoid granulations
What is the dural venous sinus that contains arachnoid granulations?
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
How is most of the CSF absorbed?
Most of the fluid is absorbed back into the bloodstream through vessels lining branched projections from the arachnoid membrane called arachnoid villi, or granulations. These arachnoid granulations extend into the dura
What causes arachnoid granulation?
Arachnoid granulations (or arachnoid villi) are small protrusions of the arachnoid (the thin second layer covering the brain) through the dura (the thick outer layer).

Absorption at the arachnoid granulations returns CSF to the?
venous circulation

How would decreased diffusion across the arachnoid granulations affect the volume of the cerebrospinal fluid in the ventricles?
increase
What part of the brain absorbs cerebral spinal fluid?
It is reabsorbed through arachnoid granulations and goes into the venous sinus system.
Where does the csf drain from subarachnoid space?
In the brain we have small protrusions of the arachnoid and subarachnoid space into the venous system. These protrusions are called arachnoid villi or arachnoid granulations and they allow for drainage of CSF into the venous system. Another source of CSF drainage is the lymphatic system.
What is the protective covering of the brain that provides passageways for cerebrospinal fluid to drain into the superior sagittal sinus?
The arachnoid mater has specializations called arachnoid granulations that extend through the dura mater into the superior sagital space. This permits cerebral spinal fluid to enter venous circulation.
What are the consequences of blocked arachnoid villi?
Arachnoid villi can be compared to the drain in your shower or sink. Think about a wad of hair covering the drain. The water cannot drain out and if more water is added without removing the blockage, there will be a build-up of water. It is the same with your arachnoid villi. If blockage occurs, the cerebrospinal fluid won't be able to flow freely, thus building up pressure. This is called hydrocephalus or "water on the brain".
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.
