Ganglia are heterogeneously innervated by bilateral autonomic inputs, but I am in the process of confirming this in the rabbit. Neurochemical … WebThe pelvic visceral organs are innervated by branches of the second to fourth sacral nerves. The ganglia cells are typically clustered within the walls of the viscera, thereby making the parasympathetic postganglionic fibers very short. Cardiac parasympathetic innervation is principally via the tenth cranial nerve, better known as the vagus nerve.
