The arachnoid mater is part of the meninges, which are three layers of membranes that cover and protect your brain and spinal cord (your central nervous system). 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.. I was always treated with respect and explained everything throughly, that made it easy for everyone to understand. This may relate to any interval spinal intervention, infection or trauma during this period. CES most commonly results from a massive herniated disc in the lumbar region.
