Cerebrospinal Fluid. Cerebrospinal fluid, also called CSF,is a clear fluid that surrounds the spinal cord and brain. The flow of CSF is essential to the cushioning, protection and support of the brain. It is also essential for the removal of waste products from the brain.SF is produced in the chambers of the brain called ventricles. The two highest ventricles in the brain are the lateral ventricles. The third ventricle lies below them and the fourth ventricle lies below the third. A dense plexus of blood vessels, called the telea choroidea, lies close to the ventricles.
