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.
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
The function that reabsorbs cerebral spinal fluid back into the blood is called arachnoid villi or arachnoid granulations. These structures are responsible for draining CSF from the subarachnoid space into the bloodstream, helping to maintain the fluid balance in the brain.
No, cerebrospinal fluid is produced by the choroid plexus in the brain's ventricles. Arachnoid villi function to reabsorb and return cerebrospinal fluid back into the bloodstream.
Most of the cerebrospinal fluid (CSF) is absorbed through structures called arachnoid granulations, also known as arachnoid villi. These are finger-like projections of the arachnoid mater that extend into the venous sinuses of the brain, allowing CSF to be reabsorbed back into the bloodstream.

it reabsorbs cerebrospinal fluid and returns it to the venous circulation

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".
Cerebrospinal fluid is reabsorbed into the bloodstream through structures called arachnoid granulations, located in the membranes surrounding the brain. These granulations allow for the transfer of CSF from the subarachnoid space into the venous sinuses of the brain.
Arachnoid granulations are caused by the body's normal process of reabsorbing cerebrospinal fluid (CSF) within the brain. These structures are responsible for draining CSF from the subarachnoid space back into the bloodstream.
The small intestine is lined with microscopic fingerlike strutcures called villi which increase the surface area of the small intestine fo absorption. The spaces between villi are like a sieve that absorb the food particles into the bloodstream. There are three types of villi. Intestinal Villi which lines the intestines, Chorionic Villi which is on the outer most membrane of a fetus and Arachnoid Villi which is on the arachnoid membrane of the brain.
Cerebrospinal fluid (CSF) drains from the subarachnoid space into the bloodstream through structures called arachnoid granulations or arachnoid villi. These structures are located within the dural venous sinuses of the brain. Here, CSF is reabsorbed into the bloodstream, helping to maintain the balance of this important fluid surrounding the brain and spinal cord.
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.
