查询词典 root canal

The pelvic nerve of inferior hypogastric plexus originated from the most caudal root of the pelvic splanchnic nerve, running along the surface of the levator ani and passing laterally around the vagina and rectum to enter the sphincter musculature at the 5-o'clock and 7-o'clock positions. 7l.4% of specimens were found intrapelvic branches which were given by pudendal nerve. Before leaving the pudendal canal, pudendal nerve gave an intrapelvic branch that passed the levator ani and accompanied with pelvic nerve to innervate the sphincter when it approached the sphincter. The distance between these intrapelvic branches and the level of the bladder neck was about (12.6±1.6)mm.

结果：控尿神经是由下腹下丛和阴部神经盆内盆外分支组成，其中盆神经是下腹下丛远端盆内脏神经分支，沿肛提肌表面到达尿道5点和7点位。71.4%的标本中发现阴部神经存在盆内分支，此分支自阴部管内的阴部神经主干穿肛提肌进入盆内，大约在接近尿道括约肌时汇入盆神经共同进入尿道括约肌，其进入尿道的位置距离膀胱颈平面(12.6±1.6)mm。
