In the human fetus of 14 weeks, ganglia on either sides of the Müllerian uterovaginal canal contained two types of cells. In the 16th week, axons invaded the basal zone of the stratified squamous epithelium at the sides of the upper vagina. In the 20th week, vesicular nuclei typified the large neurons in the midportion of the cervico-vaginal ganglion. During the 22nd week, capsulated ganglia invaded the wall of the upper vagina forming three concentrically disposed strata. Non-capsulated clusters invaded its lamina propria. At the 24th week, axons were shaded after reaching the superficial zone of the stratified vaginal epithelium. In the 28th week, satellites surrounded the mature neurons and sheath cells enveloped the axons. Ganglia invaded the splitted muscle layer of the upper vagina at 30 weeks. Intraepithelial fibres invaded the whole thickness of the endometrium, the columnar epithelium of the cervix and uterine tube at 40 weeks. Nerve cells were detected among the basal epithelial cells of the lower vagina and its subepithelial plexus.
在14周大的人类胎儿中，苗勒管子宫阴道段两侧的神经节含有两种类型的细胞。在第16周时，轴突侵入阴道上段两侧复层鳞状上皮的基底层。在第20周时，泡状核是宫颈阴道神经节中部大神经元的典型特征。在第22周时，有被膜神经节侵入阴道上段壁，形成三个同心排列的层。无被膜神经簇侵入其固有层。在第24周时，轴突到达阴道复层上皮的表层后变细。在第28周时，卫星细胞围绕着成熟神经元，鞘细胞包裹着轴突。在第30周时，神经节侵入阴道上段的分裂肌层。在第40周时，上皮内纤维侵入子宫内膜全层、宫颈柱状上皮和输卵管。在下段阴道的基底上皮细胞及其上皮下丛中检测到神经细胞。
