A study has been made, using an electronic microscope, of the mucosa of the lower third of the ureter of rats, including a description of three kinds of cells with their own ultrastructural characteristics. One may emphasize the presence of intraepithelial nerve endings and chromaffin type granular formations. In some cells, adjacent to the basal membrane, there is also a perinuclear structure described, consisting of tonofilaments (perinuclear crown of tonofilaments) which it is thought could affect the genesis of distension stimuli.
利用电子显微镜对大鼠输尿管下三分之一段的黏膜进行了一项研究，其中描述了三种具有自身超微结构特征的细胞。可以强调上皮内神经末梢和嗜铬细胞型颗粒结构的存在。在一些与基底膜相邻的细胞中，还描述了一种核周结构，它由张力丝组成（张力丝核周冠），据认为这种结构可能影响扩张刺激的产生。
