The ventriculus mesencephali in the rat proceeds in the colliculi posterior region from the mesencephalic aqueduct in the dorsal direction. The ependymal lining is formed by flat, cuboid and cylindrical cells. The cylindrical cells, which occur in all parts of the ventriculus mesencephali, are the most numerous. The cuboid cells are localized mainly in the anterior part, the flat ones in the posterior part of the ventriculus mesencephali. Some cuboid and cylindrical cells have short basal processes. Among the ependymal cells, there are cells with long basal processes. The ependyma is at sites interrupted by flocks of ependymal cells. On the cell surface, there area cilia, microvilli and protoplasmic extrusions. The cell nuclei are spherical to oval. Supraependymally, there are homogeneous globules and intraventricular fibres. The histological variability of ependymal cells may point to the active participation of these cells in functional processes, even within such a small part of the ventricle system as the ventriculus mesencephali.
大鼠中脑导水管在中脑后部区域从背侧方向通向中脑导水管。室管膜衬里由扁平、立方和柱状细胞组成。柱状细胞在中脑导水管的所有部位都有,数量最多。立方细胞主要位于中脑导水管的前部,扁平细胞位于后部。一些立方和柱状细胞有短的基底突起。在室管膜细胞中,有长基底突起的细胞。室管膜在某些部位被成群的室管膜细胞中断。在细胞表面,有纤毛、微绒毛和原生质突起。细胞核呈球形至椭圆形。在室管膜上方,有均匀的小球和脑室内纤维。室管膜细胞的组织学变异性可能表明这些细胞积极参与功能过程,即使是在脑室系统如此小的一部分,如中脑导水管。
