Question

Quizplus · Accepted Answer

CSF is formed by choroid plexuses, which are clusters of capillaries in the ventricular walls. It is reabsorbed through arachnoid granulations, also known as arachnoid villi, into the dural sinuses. Option A is incorrect because dural sinuses do not play a role in the formation of CSF. Option B is incorrect because the cerebral aqueduct is not involved in the reabsorption of CSF. Option D is incorrect because astrocytes do not play a role in CSF formation or reabsorption.
