The normal adult human round window membrane was examined by transmission electron microscopy. The membrane consists of the following three layers: (1) an outer squamous epithelial layer with an underlying basement membrane; (2) a middle fibrous layer containing collagen, elastin, fibrocytes, vessels, and nerves; and (3) an inner layer of mesothelial cells. Mucosal membrane veils that cover the round window membrane, forming "false" round window membranes, are also described. These membranes are also three layered, including (1) an outer epithelial layer with an underlying basement membrane, (2) a middle fibrous layer containing collagen, elastin, fibrocytes, vessels, and nerves, and (3) an inner epithelial layer with an underlying basement membrane. Ultrastructural differences between these two structures are discussed.
通过透射电子显微镜对正常成年人类圆窗膜进行了检查。该膜由以下三层组成：（1）外层为鳞状上皮层，其下方有基底膜；（2）中层为纤维层，包含胶原蛋白、弹性蛋白、纤维细胞、血管和神经；（3）内层为间皮细胞层。还描述了覆盖圆窗膜形成“假”圆窗膜的黏膜瓣。这些膜也是三层结构，包括（1）外层上皮层及其下方的基底膜，（2）中层纤维层，含有胶原蛋白、弹性蛋白、纤维细胞、血管和神经，（3）内层上皮层及其下方的基底膜。讨论了这两种结构之间的超微结构差异。
