A scanning electron microscopic study of the endolymphatic sac of the mongolian gerbil is presented. As described in other animal species and in man, three rather distinct regions on the epithelial surface can also be recognized in this rodent. Light and dark cells are seen to line the sac epithelium throughout. At the level of the intermediate portion, however, a different cell type--the granular cell--is present, with its luminal surface covered by large amounts of solid material. On the basis of light and transmission electron microscopic studies presented elsewhere, a higher degree of functional specialization in this portion of the gerbilline sac is proposed.
本文呈现了对蒙古沙鼠内淋巴囊的扫描电子显微镜研究。正如在其他动物物种和人类中所描述的那样，在这种啮齿动物的上皮表面也可识别出三个相当不同的区域。整个囊上皮都可见明细胞和暗细胞排列。然而，在中间部分的水平，存在一种不同类型的细胞——颗粒细胞，其腔面覆盖有大量固体物质。基于其他地方所呈现的光镜和透射电子显微镜研究，提出沙鼠囊这一部分具有更高程度的功能特化。
