All nerves in the body have a blood supply to maintain their function and health, typically provided by small blood vessels called vasa nervorum. These vessels supply oxygen and nutrients to the nerve tissues. Therefore, while the sciatic nerve is one of the largest nerves, it is not unique in having a blood supply.
