Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialised ependymal cells in the choroid plexus 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. CSF acts as a shock absorber, cushion or buffer, providi… WebJul 31, 2014 · Increased CSF osmolarity reversibly induces hydrocephalus in the normal rat brain. Fluids and Barriers of the CNS 2012;9:13). Further support for the concept of osmotic gradients resulting in hydrocephalus comes from experiments focusing on the development of ventricles in embryos.
