Describe the role and circulation of cerebrospinal fluid in the nervous system. Cerebrospinal fluid (CSF) is a clear, colorless bodily fluid that occupies the subarachnoid space and the ventricular system around and inside the brain and spinal cord.
The term hydrocephalus comes from the Greek words âhydro,â which means water, and âcephalus,â meaning head. Simply put, hydrocephalus is excessive accumulation of fluid in the brain. While once known as âwater on the brain,â the âwaterâ is actually cerebrospinal fluid (CFS). The excessive accumulation of cerebrospinal fluid (CSF) results in an abnormal widening of spaces in the brain called ventricles.
