👉 The Nav Fluid, also known as the Navicelular Fluid, is a specialized form of cerebrospinal fluid that surrounds and cushions the brain and spinal cord within the protective sacs called ventricles in the central nervous system. This fluid plays a crucial role in maintaining the health of neural tissues by providing essential nutrients, removing waste products, and acting as a shock absorber to protect the delicate brain and spinal cord from mechanical impacts. The Navicelular Fluid is continuously produced by the choroid plexus and reabsorbed by the ependymal cells lining the ventricles, maintaining a delicate balance that is vital for optimal brain function.
