Quizplus · Accepted Answer

Arachnoid granulations are small protrusions of the arachnoid mater that extend into the venous sinuses of the brain. These granulations serve as one-way valves, allowing cerebrospinal fluid (CSF) to flow from the subarachnoid space into the venous circulation. This is important for regulating CSF pressure and volume within the brain. The other options are not accurate descriptions of arachnoid granulations.
