1下泌尿道的神经支配下泌尿道的神经分布来源于交感、副交感和躯体髓状神经元及其传入和传出神经纤维。由此，膀胱和尿道平滑肌均接受交感和副交感神经的双重支配。尿道外括约肌内的根级肌主要是以耻骨神经为主的躯体神经支配。膀胱体部和顶部主要接受来自骨盆神经的副交感神经
1 The innervation of the urinary tract under the innervation of the lower urinary tract is derived from sympathetic, parasympathetic and somatic medullary neurons and their afferent and efferent nerve fibers.

The body and top of the bladder mainly accept the parasympathetic nerve from the pelvic nerve
