👉 The collected fluid, often referred to as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates around the brain and spinal cord. It serves multiple crucial functions, including cushioning and protecting these vital structures from mechanical shock, maintaining a stable chemical environment by regulating ion concentrations, and facilitating the removal of metabolic waste products. The fluid is produced primarily by the choroid plexus and the arachnoid villi, and it circulates through the ventricles of the brain before draining into the bloodstream. Analyzing the composition and properties of CSF can provide valuable insights into neurological health, helping to diagnose conditions such as meningitis, multiple sclerosis, and hydrocephalus.
