Ependymal cells are also neuroglial cells, and they're cuboidal-to-columnar - so square to rectangular shaped - ciliated cells that line the ventricles and central canal.

室管膜细胞也属于神经胶质细胞，呈立方或柱状，部分带有纤毛，排列在脑室和脊髓中央管内。

Now, again, they can form in the brain and spinal cord because that's where ependymal cells are found, but pediatric ependymomas tend to form in the fourth ventricle.

同样，它们可以在大脑和脊髓中形成，因为这些地方分布着室管膜细胞，但儿童室管膜瘤往往在第四脑室形成。
