What drains cerebrospinal fluid in to venous blood in the dural sinus?

Cerebrospinal fluid is drained into venous blood in the dural sinuses through structures called arachnoid granulations (also known as arachnoid villi or pacchionian bodies). These specialized projections of the arachnoid mater penetrate through the dura mater into the superior sagittal sinus and other dural sinuses, where they allow for the reabsorption of cerebrospinal fluid into the bloodstream.


What are finger like structures that project into the dural sinuses to allow drainage of the csf?

Arachnoid granulations are finger-like structures that project into the dural sinuses. They absorb cerebrospinal fluid (CSF) from the subarachnoid space and allow for its drainage into the bloodstream.


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 are cavities that filled with blood and help drain cerebrospinal fluid?

Cavities that are filled with blood and help drain cerebrospinal fluid in the brain are called the arachnoid granulations. These structures play a key role in maintaining the balance of cerebrospinal fluid in the central nervous system.


Where are Dural venous sinuses found?

Dural venous sinuses are found between the periosteal and meningeal layers of the dura mater, which is the outermost layer of the meninges surrounding the brain. These sinuses drain blood and cerebrospinal fluid from the brain and ultimately connect to the internal jugular vein.

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 found within the dural sinuses of the brain?

The dural sinuses are blood-filled channels located between the layers of the dura mater, the outermost membrane surrounding the brain. They collect blood from the brain and drain it back into the systemic circulation through the internal jugular vein. The sinuses contain venous blood, cerebrospinal fluid, and arachnoid granulations.

Venous channel between the two outermost meninges?

dural sinus


What is the most common name given to these venous sinuses?

Dural sinus


Where does the subdural space lie between?

The subdural space lies between the dural and arachnoid layers of the meninges.


What is the meaning of external dural?

There are three membranes covering the brain.  The Pia Mater, the Arachnoid Mater and the Dura Mater.  Extra Dural means that something is outside the Dura Mater.


What is the space created when the dural layers separates?

The space created when the dural layers separate is called a dural venous sinus. These sinuses are responsible for draining blood and cerebrospinal fluid from the brain and are located between the layers of the dura mater.
