The fingerlike projections that extend into the dural venous sinuses and reabsorb cerebrospinal fluid into the blood are known as arachnoid granulations or arachnoid villi. The arachnoid membrane is located between the dura mater and pia mater layers of the meninges and houses the cerebrospinal fluid. The arachnoid granulations protrude through the dura mater into the dural venous sinuses where cerebrospinal fluid is returned to the bloodstream.
