Cerebellar Cortex Folia

CSF Flow through the brain

secreted by Choroid Plexus through intraventricular foramina choroid plexus in third ventricle adds more CSF down through cerebral aquaduct choroid plexus in fourth ventricle adds more CSF out 2 lateral and one median aperature fills subarachnoid space covering external surface of brain and spinal cord arachnoid villi reabsord in venous blood of dural venous sinuses

CSF Flow 1

Secreted by choroid plexus in each lateral ventricle

CSF Flow 2

flows through intraventricular foramina into third ventricle

CSF Flow 3

Chrooid plexus in third ventricle adds more CSF

CSF Flow 4

CSF flows down cerebral aquaduct to fourth ventricle

CSF Flow 5

Choroid plexus in fourth ventricle adds more CSF

CSF Flow 6

CSF flows out 2 lateral and one median aperature

CSF Flow 7

CSF fills subarachnoid space and bathes external surfaces of brain and spinal cord

CSF Flow 8

Arachnoid villi reabsorb CSF into venous blood of dural venous sinuses
