Front 15

flow of CSF

Back 15

secreted by choroid plexus in lateral ventricle --> flows through interventric. foramina to 3rd vent. --> 3 vent. choroid plexus adds more CSF --> flows down cerebral aquaduct to 4th vent. --> choroid plex. of 4th vent. adds more CSF --> flows out to 2 lateral apertures and one median apenture --> fill subarach. space and bathe external surface of brain and SC --> at arach. villi CSF reabsorbed into venous blood of duran venous sinuses
