👉 The kernel fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that surrounds and protects the brain and spinal cord. It acts as a cushion, providing mechanical protection and maintaining a stable environment for these vital organs. The fluid also facilitates the exchange of nutrients, waste products, and gases between the bloodstream and neural tissues. Produced by the choroid plexus within the ventricles of the brain, it circulates through the ventricular system and into the subarachnoid space surrounding the spinal cord, ensuring optimal function and health of the central nervous system.
