Résumé : An illustrated account is given of the innervation of the ureter demonstrating the existence of adrenergic (orthosympathetic) and cholinergic (parasympathetic) nerve fibres. Close neuromuscular junctions (150 to 500 Å) are occasionally observed between terminal nerve fibers and smooth muscule fibers. The smooth muscle cells are brought into 'contact' by zones of specialized fusion (nexus), sites of least resistance to the electrical transmission of peristaltic activity. Ganglionic structures are observed in the adventia of the terminal ureter and the ureterovesical junction. These ganglia are made up of main neurons and small granular cells containing catecholamines. The significance of the adrenergic cells is discussed and a model of ureteral innervation is postulated.
