Question

Quizplus · Accepted Answer

Cerebrospinal fluid is produced by the choroid plexuses in the ventricles and it serves to protect the brain from blows to the skull by acting as a cushion. While it does help with maintaining a stable ionic concentration and moistening the surface of the brain, these are not the primary functions of CSF. Additionally, arachnoid villi provide a pathway for CSF to enter the bloodstream, but this is not the direct function of CSF production.
