The human amnion was examined by means of light microscopy and scanning and transmission electron microscopy. The surface shows apart from microvilli a particular structure, called "blebs"; the intercellular junction is formed by desmosomes and a labyrinthine channel system, and at the base pedicels extend into the basement membrane. Cell shedding uncovers the basement membrane which seems to play a primordial role in preserving the intact amniotic cavity. These data underline the complex structure and the multiple role the amnion performs during gestation.
通过光学显微镜、扫描电子显微镜和透射电子显微镜对人羊膜进行了检查。其表面除微绒毛外还呈现一种特殊结构，称为“泡”；细胞间连接由桥粒和复杂的通道系统形成，在基部，蒂延伸至基底膜。细胞脱落会暴露基底膜，基底膜似乎在维持羊膜腔完整方面起着重要作用。这些数据突显了羊膜在妊娠期间所具有的复杂结构和多种功能。
