Fluid that surrounds the brain and spinal cord is referred to as what?

The fluid that surrounds the brain and spinal cord is known as cerebrospinal fluid. This specialized fluid is critical for various functions within the central nervous system. It provides cushioning, protecting these sensitive structures against physical trauma, and helps to maintain stable pressure within the cranial cavity. Furthermore, cerebrospinal fluid plays a vital role in the circulation of nutrients, the removal of waste products, and serving as a medium for the transportation of various signaling molecules essential for neural function. Its unique composition is specifically adapted to meet the metabolic needs of the nervous system, which differentiates it from other bodily fluids.
