Cerebrospinal Fluid Pathway Diagram
Cerebrospinal fluid csf is a clear colorless body fluid found in the brain and spinal cord it is produced by specialised ependymal cells in the choroid plexuses of the ventricles of the brain and absorbed in the arachnoid granulations there is about 125 ml of csf at any one time and about 500 ml is generated every day.
