👉 The segments fluid, also known as the cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system (CNS). It surrounds and cushions the brain and spinal cord, providing essential protection against physical shocks and reducing the risk of injury. The fluid also plays a critical role in maintaining the homeostasis of the CNS by regulating temperature, nutrient transport, and waste removal. Additionally, it helps in the removal of metabolic waste products from neural tissues. The production and circulation of CSF are tightly regulated by the choroid plexus, a network of blood vessels and specialized cells in the ventricles of the brain, ensuring a constant supply to support optimal neural function.
