| 摘 要： | 应用扫描和透射电子显微镜观察研究大鼠中脑水管室管膜的超微结构特征。发现中脑水管壁具有平行走向的纵嵴，腔面被覆单层立方或柱状上皮；上皮细胞游离面可见大量纤毛、微绒毛及分泌泡；细胞核圆形，位于细胞中央；胞浆内细胞器分布具有明显的极性特点。通过超微结构研究，认为大鼠中脑水管不仅单纯是脑脊液引流的通路，而且还具有主动参与脑脊液分泌的功能。

| Abstract: | The ultrastructural characteristics and their functions of ependymal epithelium of the cerebral aqueduct in rats were studied by transmission and scanning electron microscopy.Along the cerebral aqueduct there were longitudinal parallel cristae,which was lined by simple cuboidal or columnar epithelium.On the free surface of epithelial cells there were numerous cilia,microvilli and microapocrinal vesicles.A spherical nucleus situated in the middle part of the cell and the distribution of its organelles showed apparent polarity.According to the ultrastructural characteristics of ependymal epithelium of the cerebral aqueduct in rats,we concluded that they were not only drainage tube but also make positive participation in the secretion of cerebrospinal fluid. |
