Question

Quizplus · Accepted Answer

Arachnoid villi are small protrusions of the arachnoid mater that extend into the dural sinuses, through which CSF is reabsorbed into the bloodstream.

Answer: B
 The subarachnoid space is the area between the arachnoid mater and pia mater that contains CSF.

Answer: C
 Choroid plexuses are specialized structures in the ventricles of the brain that produce CSF.

Answer: D
 Dural sinuses are large veins located between the layers of the dura mater that drain venous blood from the brain and carry CSF reabsorbed by the arachnoid villi.

Answer: E
 The dura mater is the outermost and toughest layer of the meninges that encloses the brain and spinal cord. It does not play a direct role in the production or flow of CSF.
