The Sympathetic Innervation of the Urinary Bladder and Urethra in the Normal State and After Parasympathetic Denervation at the Spinal Root Level: An Experimental Study in Cats

摘要: The innervation of the feline bladder and urethra was studied by a histochemical fluorescence technique use peripheral nerve stimulations in combination with different blocking agents. studies were performed normal state at various times after parasympathetic denervation, achieved sectioning appropriate ventral roots.After denervation response following hypogastric stimulation changed from initial contraction subsequent relaxation into sustained contraction. This altered response, first observed 6 weeks, composed two phases; weak brief followed immediately strong long-lasting second phase adrenergic (blocked an aL-blocking agent) presumably effected via intramural ganglia ganglionic agent).Consistent this observation change innervation. About weeks ...
