Which fluid bathes the neurons of the brain and spinal cord and cushions against the bumps and jolts?

Explanation

Blood is a specialized bodily fluid that circulates throughout the body via the circulatory system, delivering oxygen and nutrients. Interstitial fluid is a clear, colorless fluid that surrounds and bathes the cells of tissues in the body. It is derived from the blood plasma that leaks out of the capillaries and into the interstitial space, which is the space between the cells and the blood vessels. Intracellular fluid (ICF) is the fluid that is present inside the cells of the body. It is one of the two main compartments of body fluid, the other being extracellular fluid (ECF), which includes interstitial fluid, blood plasma, and other fluids outside of the cells. Cerebrospinal fluid (CSF) is a clear, colorless liquid that surrounds the brain and spinal cord. CSF serves several important functions in the central nervous system. It helps to cushion and protect the brain and spinal cord from injury, providing buoyant support for the delicate structures of the brain.
