Question

Quizplus · Accepted Answer

Cerebrospinal fluid is formed by the choroid plexuses located in the ventricles of the brain.

Option B is incorrect because arachnoid villi are responsible for the absorption of cerebrospinal fluid back into the bloodstream.

Option C is incorrect because the blood-brain barrier is formed by specialized cells lining the walls of blood vessels in the brain, not by cerebrospinal fluid.

Option D is incorrect because cerebrospinal fluid does not separate the dura mater from the skull bone.
