BranchFrom	Thoracic ganglia

lesser splanchnic nerve: superior mesenteric ganglion and aorticorenal ganglion least splanchnic nerve: renal plexus Thoracic splanchnic nerves are splanchnic nerves that arise from the sympathetic trunk in the thorax and travel inferiorly to provide sympathetic supply to the abdomen. The nerves contain preganglionic sympathetic fibers and general visceral afferent fibers.

Nerves

There are three main thoracic splanchnic nerves.

Name	Spinal Nerve Roots
Greater splanchnic nerve	T5–T9	T5–T9
Lesser splanchnic nerve	T9–T12	T9–T12
Least splanchnic nerve	T12	T12–L2
