It also encloses the cerebrospinal fluid, a nurturing fluid that also cushions the brain against impact. The folds of the dura mater also form venous channels through which deoxygenated blood flows before reaching the jugular and ophthalmic veins to leave the cranium. As the nerves of the central nervous system exit to the periphery, the dura mater will merge with the nerves to separate the individual fibers, becoming the endoneurial connective tissue of the peripheral nerve.
