Question

Quizplus · Accepted Answer

CSF is reabsorbed into the blood supply via the arachnoid granulations, also known as the arachnoid villi. These structures are located in the arachnoid mater and function to transfer CSF from the subarachnoid space to the venous sinuses of the dura mater, where it is then absorbed into the bloodstream. The choroid plexus is responsible for producing CSF, not reabsorbing it. The foramen of Magendie and the nodes of Ranvier are not involved in the reabsorption of CSF. The dura mater also does not play a significant role in the reabsorption of CSF.
