Summary Histochemical techniques for acetylcholinesterase and catecholamine show that ureterovesical ganglia of both cat and dog contain dense intraganglionic cholinergic and adrenergic plexuses. Ramifications of both plexuses surround most cholinergic and adrenergic ganglion cell bodies as pericellular synaptic plexuses. Similar pericellular plexuses exist around extraganglionic cholinergic and adrenergic ganglion cells. Both adrenergic and cholinergic synaptic fibers persist in denervated pregnaglionic nerve-free specimens, indicating that cholinergic synaptic fibers are postganglionic parasympathetic in nature. The presence of adrenergic (postganglionic sympathetic) and postganglionic parasympathetic synapses around cell bodies in ureterovesical ganglia provides a morphologic basis for the sympathoinhibitory and muscarinic parasympatho-excitatory phenomena described in these ganglia.
