Quizplus · Accepted Answer

Arachnoid granulations, also known as arachnoid villi, are small protrusions of the arachnoid mater into the dural sinuses. They function to reabsorb cerebrospinal fluid (CSF) back into the bloodstream, specifically into the venous blood of the dural sinuses. This process helps maintain the balance of CSF within the central nervous system.
