Cerebrospinal fluid ('''CSF''') surrounds the brain as well as the central canal of the spinal cord. It helps cushion the central nervous system (CNS), acting in a similar manner to a shock absorber. It also acts as a chemical buffer providing immunological protection and a transport system for waste products and nutrients. The CSF also provides buoyancy to the soft neural tissues which effectively allows the neural tissue to "float" in the CSF. This prevents the brain tissue from becoming deformed under its own weight.

It acts as a diffusion medium for the transport of neurotransmitters and neuroendocrine substances.
