The ciliated ependyma of the hypothalamus of the hanster (Cricetus cricetus) consists of a sheet of cells, the luminal surface of which is reflected over cilia and numerous microvilli. The lateral portions of the plasmalemma of contiguous cells are fused at some sites to from junctions of five layers, the zonula occludens. These fusions occur usually in continuity with other intercellular junctions, the zonula adhaerens. In the apical regions of the ependyma these fusions are almost spiralled. The nucleus is regularly oval and lying close to the basal plasmalemma. The cytoplasm contains a finely granular matrix, filamentous components close to the junctions. The endoplasmic reticulum is sparse. The Golgicomplex is confined to the supranuclear cytoplasm, and mitochondria, are more numerous in the apical than in the basal regions of ependymal cells; the mitochondria are generally rounded and have transverse cristae and granules. The apical regions of the cytoplasm contain the basal bodies of cilia; they form non-striated rootlets and the rootlet filaments tend to diverge, ending in a granular zone.
仓鼠（黑线仓鼠）下丘脑的纤毛室管膜由一层细胞组成，其腔面反折覆盖在纤毛和众多微绒毛上。相邻细胞质膜的外侧部分在某些部位融合形成五层连接，即紧密连接。这些融合通常与其他细胞间连接，即黏着连接连续出现。在室管膜的顶端区域，这些融合几乎呈螺旋状。细胞核呈规则的椭圆形，靠近基底质膜。细胞质含有细颗粒状基质，靠近连接部位有丝状成分。内质网稀疏。高尔基体局限于核上细胞质，线粒体在室管膜细胞顶端区域比基底区域更多；线粒体通常呈圆形，有横嵴和颗粒。细胞质的顶端区域含有纤毛的基体；它们形成无横纹的小根，小根丝趋于发散，终止于颗粒区。
