Aorticorenal ganglion

The aorticorenal ganglion is composed of the superior mesenteric, renal, and inferior mesenteric ganglia. This is distinct from the celiac ganglia. However, they are part of the preaortic ganglia.

Anatomical terms of neuroanatomy

Sympathetic input to the gut comes from the sympathetic chain next to the thoracic vertebrae. The upper nerve supply arrives from cell bodies at the levels of T5–T9, leaves the sympathetic chain by the greater splanchnic nerve, and synapses in the celiac ganglion before proceeding onto the foregut. Below this the lesser splanchnic nerve arises from T10–T11, leaves the sympathetic chain and synapses at the aorticorenal ganglion before going onto also supply the kidney and upper ureter. Below this the least splanchic nerve arises from T12 and leaves the sympathetic chain to synapse at the "renal plexus."

The preganglionic ventral root of the least splanchnic nerve originates from vertebral level T12, and enter the abdominal cavity by piercing the crus of the diaphragm.
