Greater Splanchnic Nerve

The preganglionic fibers of the Greater Splanchnic nerve emerge from the medial aspect of T5 through T9 ganglia or intervening portions of the trunk. Contributions from these levels come off singly or in combination to form a large nerve trunk, which descends along the anterolateral aspect of the vertebral column. It variably perforates the crus of the diaphragm to terminate in the celiac ganglion. The postganglionic fibers extend to the stomach, liver, spleen, and kidney.
