Question

Quizplus · Accepted Answer

Cerebrospinal fluid is primarily formed by the choroid plexus, which are specialized structures found in the ventricles of the brain. These structures produce and secrete the cerebrospinal fluid, which then circulates through the ventricles and into the subarachnoid space surrounding the brain and spinal cord. Arachnoid villi and granulations are involved in the absorption of cerebrospinal fluid back into the bloodstream, while the septum pellucidum and mesencephalic aqueduct are not directly involved in the formation or circulation of cerebrospinal fluid.
