What does CSF means?

CSF stands for cerebrospinal fluid, which is a clear, colorless liquid that surrounds and protects the brain and spinal cord. It serves several functions, including cushioning the central nervous system, providing buoyancy, and facilitating the removal of waste products. CSF is produced in the brain's ventricles and circulates through the subarachnoid space and around the spinal cord. It plays a crucial role in maintaining homeostasis within the central nervous system.
