The lesser thoracic splanchnic nerves pass to the aorticorenal ganglia, located at the branching of the renal arteries from the abdominal aorta. Postsynaptic fibers pass laterally to form the renal plexus along the renal vessels, and also inferiorly, to enter the intermesenteric plexus lying on the aorta between the superior and inferior mesenteric arteries.

The least thoracic splanchnic nerve does not pass to an identifiable ganglion, but rather enters the renal plexus and synapses on diffuse ganglion cells there.

Parasympathetic fibers also enter the renal plexus after passing down through the celiac ganglia.
