Question

Quizplus · Accepted Answer

Choroid plexuses are the structures located in the ventricles of the brain that produce cerebrospinal fluid (CSF).

Answer: A
 Arachnoid villi are finger-like projections that extend from the arachnoid mater into the dural sinuses and allow for the absorption of CSF.

Answer: B
 The subarachnoid space is the location between the arachnoid mater and the pia mater where CSF circulates and provides cushioning and nutrient exchange for the brain and spinal cord.

Answer: D
 Dural sinuses are blood-filled channels located in the dura mater, which serve as a drainage system for venous blood and CSF from the brain.

Answer: E
 The dura mater is the outermost layer of the meninges and serves as a protective covering for the brain and spinal cord. It contributes to the formation of the dural sinuses, but is not directly involved in the production or circulation of CSF.
