Question

Quizplus · Accepted Answer

Arachnoid villi are structures that protrude into the dural sinuses and allow for the reabsorption of cerebrospinal fluid into the blood.

Answer: D
 Dural sinuses are venous channels located between the endosteal and meningeal layers of the dura mater. They receive the cerebrospinal fluid that has been reabsorbed by the arachnoid villi.

Answer: C
 Choroid plexuses are structures located in the ventricles of the brain that produce cerebrospinal fluid.

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

Answer: E
 The dura mater is the tough outermost layer of the meninges, which are the protective coverings surrounding the brain and spinal cord. It does not directly participate in the reabsorption of cerebrospinal fluid.
