WebFeb 22, 2016 · Cerebrospinal fluid (CSF) is found in the subarachnoid space of the brain (within the ventricles) and spinal canal. It is produced by the choroid plexus in the ventricles of the brain and the cerebral vessels, at the rate of 500 ml/day. Production matches reabsorption so, at any one time in an adult, the average volume of CSF is about 150 ml. Web{{configCtrl2.metaDescription()}}
