👉 The corpus fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system, specifically surrounding the brain and spinal cord. It serves multiple crucial functions: providing nutrients to neural tissues, removing waste products, maintaining a stable chemical environment, and cushioning the brain and spinal cord from mechanical shock. Produced by the choroid plexus in the ventricles, it flows through the subarachnoid space, bathing the neural structures and ensuring their optimal functioning.
