The chinchilla round window membrane consists of three layers: (1) an outer epithelial layer facing the middle ear cavity with tight junctions and numerous desmosomes, (2) a middle connective-tissue layer consisting of fibroblasts, fibrocytes, collagen, elastin, capillaries, and myelinated and unmyelinated nerves, and (3) an inner cellular layer with thin cytoplasmic processes containing numerous micropinocytotic vesicles and dark granules similar in form to alpha-type glycogen. Studies of the fine structure of the normal round window membrane in animals are prerequisites to understanding the role of the round window membrane in both normal function and in diseased states such as otitis media.
（1）外层上皮层，面向中耳腔，有紧密连接和大量桥粒；（2）中间结缔组织层，由成纤维细胞、纤维细胞、胶原蛋白、弹性蛋白、毛细血管以及有髓和无髓神经组成；（3）内层细胞层，有薄的细胞质突起，含有大量微吞饮小泡和形态与α型糖原相似的深色颗粒。研究动物正常圆窗膜的精细结构是理解圆窗膜在正常功能以及诸如中耳炎等疾病状态中所起作用的先决条件。
