What is Cerebrospinal Fluid?

Explanation:
Cerebrospinal fluid is the clear, colorless liquid that surrounds and cushions the brain and spinal cord, helping to buoy the brain, maintain a stable chemical environment, and transport nutrients and waste. It circulates through the ventricular system and the subarachnoid space, is mainly produced by the choroid plexus, and is absorbed back into the bloodstream. This makes the fluid distinct from brain tissue, a network of capillaries in the ventricles, or a protective barrier in the skull—each of those options describes a different structure or tissue, not the fluid itself.
