2019-04-12 · Postganglionic neurons are the neurons of the autonomic nervous system, synapsing with the preganglionic neurons at the autonomic ganglia. They are responsible for conveying nerve impulses from the preganglionic neurons to the effector organs. The postganglionic fibers pass from these ganglia partly through the ansa subclavia to the heart, on their way they intermingle with sympathetic fibers from the vagus to form the cardiac plexus.
