The luminal topography and cell surface fine structure of the chicken and turkey excurrent duct system, which consists of the epididymal region, ductus deferens, and papillae were examined. All specimens were fixed in glutaraldehyde, cryofractured or bisected with a razor, and prepared for SEM, TEM, or LM. The mucosa of the more proximal ducts in the epididymal region was highly folded and had an epithelial lining of ciliated and onociliated Type 1 cells. The other epididymal ducts and ductus deferens had low mucosal folds lined exclusively by nonciliated Type 2 cells. The only major structural differences between the excurrent duct system of the chicken and tufkey were limited to the receptaculum, a sac-like dilation of the distal ductus deferens, and the gross external structure of the papillae. Variation in the surface fine structure of the Type 1 and Type 2 cells suggests that they have secretory and nonsecretory phases.
对鸡和火鸡的输出管道系统的管腔形态和细胞表面精细结构进行了检查，该系统由附睾区域、输精管和乳头组成。所有标本均用戊二醛固定，进行冷冻断裂或用剃须刀对半切开，然后制备用于扫描电子显微镜（SEM）、透射电子显微镜（TEM）或光镜（LM）观察。附睾区域近端管道的黏膜高度折叠，有一层由纤毛和单纤毛1型细胞组成的上皮内衬。其他附睾管道和输精管有低黏膜皱襞，仅由非纤毛2型细胞内衬。鸡和火鸡的输出管道系统之间唯一主要的结构差异仅限于贮精囊，即输精管远端的囊状扩张，以及乳头的大体外部结构。1型和2型细胞表面精细结构的变化表明它们具有分泌期和非分泌期。
