👉 The fluid, often referred to as cerebrospinal fluid (CSF), is a clear, colorless, and slightly yellowish liquid that circulates within the central nervous system (CNS). It is primarily produced by the choroid plexus in the ventricles and flows through the brain and spinal cord, providing essential functions such as cushioning and protecting neural tissues from mechanical shocks, regulating intracranial pressure, and removing metabolic waste products. Fluid dynamics within the CNS are crucial for maintaining homeostasis; any disruption in fluid production or absorption can lead to conditions like hydrocephalus, where an excess of fluid accumulates, increasing intracranial pressure and potentially causing neurological deficits.
