Title: [Innervation of the urinary bladder of Ovis aries L]. Author: Gentile R, Sciscioli V, De Metrio G, Lenti M, Passantino G. Journal: Boll Soc Ital Biol Sper; 1983 Dec 30; 59(12):1761-6. PubMed ID: 6671034. Abstract: The authors have extended a preliminary study about the innervation of urinary bladder, confirming the previous results pointing out the presence of metasympathetic ganglions in the wall of urinary bladder. Therefore nine urinary bladders of Ovis aries of different age and both sexes have been studied by Ruffini, Bodian and Bielschowsky's staining methods. It's possible summarize the data on the innervation of urinary bladder in the following way: in the tunica adventitia there are motor and sensitive bundles of myelinated nervous fiber. The formers, after many divisions, penetrate into the tunica muscularis contacting bundles of smooth muscle fibers, while the latters after several divisions after giving rise to thinner bundles, produce Pacini-like and Ruffini-like sense corpuscles and free nervous terminations. Furthermore, some metasympathetic ganglions of different size have been detected throughout the running of the bundles. In the tunica submucosa a diffuse and peculiar non myelinated network is observed, arising from the vegetative nervous fibers.[Abstract] [Full Text] [Related] [New Search]
