Ganglia and autonomic innervation in theCervico-thoracic region Cervicothoracicganglion: The cervico -thoracic ganglion is locatedmedial to the first rib. It isthe results of the fusion ofcaudal cervical and one ortwo thoracic ganglion. Itsend following branches: Vertebral nerveCervical cardiac nerve,&Caudal continuation ofthoracic sympathetic part.
Thoracic part of the sympathetic trunk(See Fig. Slide 14)• The number of paravertebral ganglia is correspond to the numberof thoracic vertebra.• The organs of the thoracic cavity (heart, lungs, trachea receivedautonomic innervations from Postganglionic fibers originatingfrom cervicothoracic ganglion or from postganglionic thoracicnerves.• More caudally 7-8 preganglionic thoracic fibers unite to formgreater splanchnic nerve pass through the crus of diaphragm,entered into the abdominal cavity and synapse in the celiacganglia. The postganglionic fiber from here supply to the liver,stomach, spleen, and pancreas.• Last 2-3 thoracic preganglionic fibers unite to form lessersplanchnic nerve, enter into the abdominal cavity and synapse incranial mesenteric ganglion. The postganglionic fibers from heresupply to the jejunum, ileum, cecum, colon, and kidney.
