Thethoracic ganglia areparavertebral ganglia. The thoracic portion of thesympathetic trunk typically has 12thoracic ganglia.[1] Emerging from the ganglia arethoracic splanchnic nerves (the cardiopulmonary, the greater, lesser, and least splanchnic nerves) that help provide sympathetic innervation to thoracic and abdominal structures. The thoracic part of sympathetic trunk lies posterior to the costovertebral pleura and is hence not a content of the posterior mediastinum
Also, the ganglia of the thoracic sympathetic trunk have both white and grayrami communicantes. Thewhite rami communicantes carry sympathetic fibers arising in thespinal cord into the sympathetic trunk, while thegray rami communicantes carrypostganglionic nerve fibers of the sympathetic nervous system back to thespinal nerves.
