Cerebrospinal fluid is an integral component of the anatomy and physiology of the central nervous system. It performs several vital roles that protect and support the brain and the spinal cord. When an individual is unwell, doctors may inspect the composition of cerebrospinal fluid, which can indicate certain injuries and illnesses.


1. What is Cerebrospinal Fluid?

Cerebrospinal fluid or CSF is a clear fluid found in and around the organs of the central nervous system. The fluid originates primarily in a network of ventricular cells called the choroid plexus and occupies the ventricles of the brain, the spinal cord canal and the subarachnoid spaces of both organs. The central nervous system maintains around 125 mL to 150 mL of cerebrospinal fluid.
