👉 The axis fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system (CNS), specifically around the brain and spinal cord. It serves multiple critical functions, including providing nutrients to neural tissues, removing waste products, cushioning the brain and spinal cord from mechanical shocks, and maintaining a stable chemical environment. Produced by the choroid plexus in the ventricles of the brain, the axis fluid flows through the ventricular system and into the subarachnoid space surrounding the spinal cord, ensuring optimal function and health of the nervous system.
