| | Under normal conditions, CSF is formed by the choroid plexus present within the four cerebral ventricles; the choroid plexus of the lateral ventricles producing the most. | | | The secretory process is therefore energy dependant and as a result can be influenced by drugs that affect metabolic processes. | | | It has also been suggested that a substantial amount of CSF (possibly 30%) may also be formed at sites other than the choroid plexus, particularly under pathological conditions. |

| | The choroid plexus forms the CSF and actively regulates the concentration of molecules in the CSF. | | | While the capillaries of the choroid plexus are fenestrated, non-continuous and have gaps between the capillary endothelial cells allowing the free-movement of small molecules, the adjacent choroidal epithelial cells form tight junctions preventing most macromolecules from effectively passing into the CSF from the blood (Brightman, 1968). | | | On the external surface of the brain the ependymal cells fold over onto themselves to form a double layered structure, which lies between the dura and pia, this is called the arachnoid membrane. |
