The oviduct of non-pregnant females of the ovoviviparous salamander, Salamandra salamandra, was examined using SEM-techniques. In the luminal epithelium polygonal ciliated cells were found along the entire surface of the oviduct, except the uterus, and non-ciliated cells with a varying number of short or long microvilli. The ciliated cells occur in the most anterior portion of the oviduct, the pars recta; they are sparsely distributed in the p. convoluta I, but abundant in the p. convoluta II and III. Non-ciliated cells comprise several small gland cells, restricted to the p. convoluta I, II, III, and undifferentiated cells both provided with microvilli, but difficult to be discerned from their surface appearance. The p. convoluta I, II, III is characterized by three types of secretory cells forming tubular glands, each type confined to a given zone. The secretory cells have slender microvilli at their surfaces. In freeze-cracked glands details of their secretory products can be visualized. The findings are compared to previously published TEM-investigations and discussed with regard to some functions of the oviduct during reproduction.
利用扫描电子显微镜技术对卵胎生蝾螈（火蝾螈，Salamandra salamandra）非孕雌性的输卵管进行了检查。在管腔上皮中，除子宫外，在输卵管的整个表面均发现了多边形纤毛细胞，以及具有数量不等的短微绒毛或长微绒毛的非纤毛细胞。纤毛细胞出现在输卵管最前端的直部；它们在第一盘曲部稀疏分布，但在第二和第三盘曲部数量丰富。非纤毛细胞包括几种小腺细胞，局限于第一、第二和第三盘曲部，还有均具有微绒毛的未分化细胞，但从其表面外观难以辨别。第一、第二和第三盘曲部的特征是有三种类型的分泌细胞形成管状腺，每种类型局限于特定区域。分泌细胞表面有细长的微绒毛。在冷冻断裂的腺体中，可以看到其分泌产物的细节。将这些发现与先前发表的透射电镜研究结果进行了比较，并就输卵管在生殖过程中的一些功能进行了讨论。
