Answer #1
  1. Cerebrospinal fluid is secreted by the choroid plexus into each of the lateral ventricle.
  2. Cerebrospinal fluid flows through the interventricular foramen into third ventricle.
  3. Choroid plexus in the third ventricle of the brain adds more Cerebrospinal fluid.
  4. Cerebrospinal fluid flows down cerebral aqueduct to the fourth ventricle.
  5. Choroid plexus and the fourth ventricle adds more of cerebrospinal fluid.
  6. Cerebrospinal fluid flows out into lateral apertures and one median apertures.
  7. Cerebrospinal fluid fills subarachnoid space and bathes external surfaces of brain and the spinal cord.
  8. At arachnoid villi, cerebrospinal fluid is reabsorbed into the venous blood of dural venous sinuses.
