Question

Quizplus · Accepted Answer

Arachnoid granulations are specialized projections of the arachnoid mater into the dural sinuses, which permit the reabsorption of cerebrospinal fluid (CSF) into the venous blood. The CSF is filtered through the arachnoid granulations, which contain one-way valves that prevent backflow of blood into the CSF. The filtered CSF then enters the dural sinuses and is subsequently absorbed into the venous circulation.
