👉 Nervous fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system (CNS), comprising the brain and spinal cord. It plays a crucial role in maintaining the health of neural tissues by providing essential nutrients, removing metabolic waste products, and cushioning the brain and spinal cord against mechanical shocks. Produced by specialized cells called choroid plexuses in the ventricles of the brain, CSF flows through the subarachnoid space surrounding the spinal cord and drains into the venous system via the arachnoid villi. This continuous circulation ensures optimal functioning of the CNS and protects it from potential damage.
