Abstract

The entire ductus epididymidis is characterized by pseudostratified columnar epithelium which contain principal and basal cells. Apical cells are found in the proximal segments. Long stereocilia projected from the apical surface of the principal cells. Signs of adjacent apocrine secretory activity are shown. The various segments of the ductus epididymidis present differences in the height of the epithelium, the development of the stereocilia, the appearance of granules in the cytoplasm, the luminal sperm concentration and the height of the peritubular layer.

摘要

整个附睾管的特征是假复层柱状上皮，其中包含主细胞和基底细胞。顶端细胞见于近端节段。主细胞顶端表面伸出长的静纤毛。显示出相邻顶浆分泌活动的迹象。附睾管的各个节段在上皮高度、静纤毛发育、细胞质中颗粒的出现、管腔内精子浓度和管周层高度方面存在差异。
