| Résumé : | The present study shows that the ureter possesses rich adrenergic and cholinergic innervation. The adrenergic innervation is particularly well developed in the environment of the ureter arteries, whereas the cholinergic fibers are in large numbers in the submucosa and represent the sensory receptors of the ureter. Furthermore, it was possible to identify non-adrenergic and non-cholinergic (purinergic) axons in the musculature and submucosa of the ureter, the exact function of which, however, is still unknown. The present electronmicroscopic investigations of the ureterovesical ganglia point to the existence of adrenergic intraganglionic structures enabling an integration of the sympathetic and parasympathetic influences of the function of the terminal ureter and of the urinary bladder. |
