Cerebrospinal Fluid (CSF) - Pathway of Flow 1) CSF is produced and secreted by the choroid plexus of each lateral ventricle 2) CSF flows through interventricular foramina into the third ventricle 3) Choroid plexus of the third ventricle adds more CSF 4) CSF flows down cerebral aqueduct into the fourth ventricle 5) Choroid plexus of the fourth ventricle adds more CSF 6) CSF flows out the two lateral apertures and one median aperture 7) CSF fills the subarachnoid space and bathes the external brain & spinal cord 8) At the arachnoid villi, CSF is reabsorbed into the venous blood of the dural venous sinuses By @rev.med #Cerebrospinal #Fluid #CSF #Pathway #Flow #Ventricles #neurology
