Figure 3 includes diagrams of the cauda equina nerve roots in their normal size and location. Nerve roots of the cauda equina are constantly bathed and submerged in spinal fluid that acts as a lubricant against friction between nerves, transports waste products, and brings nutrients to the nerve roots. The spinal fluid turns over about 4 times a day. Therefore, waste products, including inflammatory particles from inflamed nerve roots, are carried upward to drain through channels in the meninges into cervical lymph nodes and general circulation..
