The thoracic splanchnic nerves are visceral branches of the thoracic sympathetic trunks which are the main supply of sympathetic fibres to abdominal structures. They carry both preganglionic efferent and afferent fibres. They emerge from the fifth to the twelfth thoracic ganglia on both sides.

There are three in total:

  • greater splanchnic nerve
  • lesser splanchnic nerve
  • least splanchnic nerve
