WebTHE NORMAL CSF. The cerebrospinal fluid (CSF) is produced from arterial blood mainly by the choroid plexuses of the lateral and fourth ventricles by a combined process of diffusion, pinocytosis and active transfer. A smaller amount of CSF is also produced by ependymal cells and is derived from the interstitial fluid (ISF) of brain tissue. WebCerebrospinal fluid clearance has been traditionally believed to occur through dural venous sinuses, however, evidence for a route to lymphatic vessels in the nasal cavity has existed for over a century and half. Yet, the anatomical connections at the cribriform plate between the cerebrospinal fluid and the lymphatic system have remained unclear.
