Cerebral Spinal Fluid (CSF) is a clear, colorless liquid that surrounds the brain and spinal cord. It acts as a cushion, protecting these vital structures from injury. CSF also helps maintain stable pressure within the skull and provides nutrients to the brain while removing waste products. Produced in the choroid plexus of the brain's ventricles, CSF circulates through the subarachnoid space and is eventually absorbed into the bloodstream. This fluid plays a crucial role in maintaining the overall health of the central nervous system, ensuring that the brain and spinal cord function properly.
