It is continuous above with the thoracic poion beneath the medial lumbocostal arch, and below with the pelvic poion behind the common iliac aery.The ganglia are of small size and placed much nearer the median line than are the thoracic ganglia.Gray rami communicate pass from all the ganglia to the lumbar spinal nerves. The first and second, and sometimes the third, lumbar nerves send white rami communicates to the corresponding ganglia.The rami communicate are of considerable length, and accompany the lumbar aeries around the sides of the bodies of the veebrae, passing beneath the fibrous arches from which some of the fibres of the Psoas major arise.
