Shubham on Instagram: "Cerebrospinal fluid (CSF) is a clear, colorless liquid produced primarily by the choroid plexus that protects the central nervous system (CNS) by providing buoyancy, mechanical cushioning, waste removal, and nutrient transport. Circulating through the ventricles and subarachnoid space, it maintains ionic homeostasis for neuronal activity. Pathophysiology involves imbalances in production/absorption (hydrocephalus) or leaks, causing dangerous intracranial pressure changes.
