Cerebrospinal fluid (CSF) is a clear, colorless liquid found in your brain and spinal cord. The

brain and spinal cord make up your central nervous system. Your central nervous

system controls and coordinates everything you do including, muscle movement, organ

function, and even complex thinking and planning. CSF helps protect this system by acting

like a cushion against sudden impact or injury to the brain or spinal cord. CSF also removes

waste products from the brain and helps your central nervous system work properly.
