👉 Fluid, also known as cerebrospinal fluid (CSF), flows through the central nervous system (CNS) via a network of channels and pathways. It circulates around the brain and spinal cord, starting from the subarachnoid space and entering through the subarachnoid foramina into the ventricular system. From there, it flows through the cerebral ventricles, exits via the foramina of Luschka and Magendie into the subarachnoid space, and finally bathes the brain and spinal cord. This fluid serves multiple vital functions, including cushioning neural tissues, removing waste products, and maintaining a stable chemical environment for optimal neuronal function.
