👉 The terminal fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates around the brain and spinal cord. It acts as a protective cushion, providing mechanical support and cushioning against shocks, while also facilitating the exchange of nutrients and waste products. Produced by the choroid plexus in the ventricles, CSF flows through the ventricular system and into the subarachnoid space surrounding the brain and spinal cord. This fluid helps maintain a stable environment for neural function by regulating intracranial pressure, removing metabolic waste, and supporting the transport of essential substances. The continuous circulation and filtration processes ensure the brain remains healthy and functional.
