The ventriculus mesencephali of golden hamsters protrudes, in the form of a short channel, from the upper wall of the aquaeductus Sylvii in dorsal direction, between the third and fourth ventricle. It is lined with ependymal cells of cubic to cylindrical forms. Some of the ependymal cells possess basal processes. On the cell surface, there are cilia, microvilli and protoplasmatic protrusions. The cells contain relatively few endoplasmatic reticulum, a poorly developed Golgi apparatus, free and bound ribosomes and critiform mitochondria. The cell nuclei have round to oval shapes. Supraependymally, there are homogenous globules and intraventricular nerve fibres. The morphological characteristics of ependyma in the region of ventriculus mesencephali, as well as the close contact of the ependymal cells with capillaries, allow to suppose an active participation of these cells in the exchange of various substances also in this part of the brain ventricle system.
金黄地鼠的中脑导水管膨大部呈短管形式，从第三脑室和第四脑室之间的西尔维厄斯导水管上壁背侧方向突出。其内壁衬有立方至柱状的室管膜细胞。一些室管膜细胞具有基底突起。细胞表面有纤毛、微绒毛和原生质突起。细胞内含有相对较少的内质网、发育不良的高尔基体、游离和附着的核糖体以及嵴状线粒体。细胞核呈圆形至椭圆形。室管膜上方有均质小球和脑室内神经纤维。中脑导水管膨大部区域室管膜的形态特征，以及室管膜细胞与毛细血管的紧密接触，使得推测这些细胞在脑室系统的这一部分也积极参与各种物质的交换。
