👉 The accompanying fluid, often referred to as cerebrospinal fluid (CSF), is a clear, colorless liquid that surrounds and protects the brain and spinal cord. This fluid acts as a cushion, providing mechanical protection against impacts and shocks, while also facilitating the exchange of nutrients and waste products. It helps maintain a stable environment for the nervous system by regulating temperature, pH, and ion concentrations, and it aids in the removal of metabolic waste from neural tissues. The production and circulation of CSF are tightly regulated processes involving the choroid plexus in the ventricles of the brain and the arachnoid granulations at the spinal cord's surface.
