CSF is secreted by choroid plexus in each lateral ventricle 2. CSF flows through the interventricular foramina into the 3rd ventricle 3. Choroid plexus in the 3rd ventricle adds more CSF 4. CSF flows down the cerebral aqueduct to the 4th ventricle 5. Choroid plexus in the 4th ventricle adds more CSF 6. CSF flows – Out 2 lateral apertures and 1 median aperture Into the subarachnoid space – Down the central canal of the spinal cord 7. At the arachnoid villi, CSF is reabsorbed into the venous blood of the dural venous sinuses 20 Cross Section of Spinal cord and Vertebra 21 Spinal Cord and Meninges 22  Cranial Nerves I.
