Caudal vesical nerves

Posterior vesical nerves - (nervi vesicales posteriores, nn. vesicae caudales) - a group of nerves innervating the posterior wall of the bladder through the lesser sciatic nerve. The posterior wall of the bladder is surrounded by the processes of the sacrum. Sympathetic innervation of the bladder is carried out by the celiac nerve and its branches; parasympathetic - by the inferior mesenteric nerve, the branches of which pass inside the inferior rectus abdominis muscle along its free edge. Irritation of the brain center of the posterior nerve paralyzes all parts of the bladder. Blood supply to the posterior wall of the bladder from the internal genital system. With an infection in the genital diaphragm, the posterior wall of the bladder often becomes inflamed due to the spread of infection through the lymphatic tract. The infectious process leads to the development of paresis, which may be followed by paralysis of the muscles innervated by the posterior nerve of the bladder (bladder muscle paralysis).
