Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spine. It is produced in the choroid plexuses of the ventricles of the brain. It acts as a cushion or buffer for the brain's cortex, providing basic mechanical and immunological protection to the brain inside the skull.
Summary. The cerebrospinal fluid (CSF) is contained in the brain ventricles and the cranial and spinal subarachnoid spaces. The mean CSF volume is 150 ml, with 25 ml in the ventricles and 125 ml in subarachnoid spaces.CSF is predominantly, but not exclusively, secreted by the choroid plexuses.Brain interstitial fluid, ependyma and capillaries may also play a poorly defined role in CSF secretion.he mean CSF volume is 150 ml, with 25 ml in the ventricles and 125 ml in subarachnoid spaces.
