What is the fluid which protects the brain and spinal cord is called?

All animals have cerebrospinal fluid (CSF), a transparent, colourless bodily fluid that is present in the tissue that covers their brains and spinal cords. Specialized ependymal cells in the choroid plexus of the brain's ventricles create CSF, which is then absorbed in arachnoid granulations. About 125 mL of CSF are present at any given moment, and 500 mL are produced daily. The CSF protects the brain inside the skull mechanically and immunologically by acting as a shock absorber, cushion, or buffer. The cerebral autoregulation of cerebral blood flow is another essential role played by CSF.
