There are several in the body, including: 1  Cervical plexus-serves the head, neck and shoulders.
Thoracic splanchnic nerves are splanchnic nerves that arise from the sympathetic trunk in the thorax and travel inferiorly to provide sympathetic innervation to the abdomen.The nerves contain preganglionic sympathetic and general visceral afferent fibers. There are three main thoracic splanchnic nerves:The nerve's origins can be remembered by the 4-3-2 rule, accounting for the number of ganglia giving rise to each nerve.he nerve travels through the diaphragm and enters the abdominal cavity, where its fibers synapse at the celiac ganglia. The nerve contributes to the celiac plexus, a network of nerves located in the vicinity of where the celiac trunk branches from the abdominal aorta.
