发情期家兔输卵管上皮含有分泌细胞和纤毛细胞。分泌细胞呈气球样突起，内充满分泌颗粒。分泌颗粒均匀，有时具有界膜。它们似乎是在膜结合的空间中合成的，这里称为分泌空间，可以在细胞质的任何地方找到。没有证据表明分泌空间与高尔基带或颗粒细胞膜系统（α-细胞膜）的结构之间的关系。α-细胞膜形成发育良好的囊泡系统。不透明颗粒在细胞质中成簇出现，在分泌细胞中比在纤毛细胞中出现的程度更高。纤毛细胞具有纤毛，显示出通常的结构模式。与分泌细胞相比，纤毛细胞的胞质中只含有少量的α-细胞膜。纤毛细胞和分泌细胞的细胞核周围都有一层α-细胞膜，虽然在少数情况下在分泌细胞上发现了单个纤毛，但分泌细胞可以转化为纤毛细胞或纤毛细胞可以转化为分泌细胞的假设尚不能得到证实。
The epithelium of the Fallopian tube of rabbits in oestrus has been found to contain secretory cells and ciliated cells. Occasionally lymphocytes are encountered.The secretory cells show balloon-like bulges which are filled with secretory granules. The secretory granules are homogeneous and sometimes possess a limiting membrane. They seem to be synthetized in membrane-bounded spaces, here called secretion spaces, which can be found anywhere in the cytoplasm. No proof of a relationship between the secretion spaces and the structures of the Golgi zone or the system of granulated cytomembranes (α-cytomembranes) can be given. α-Cytomembranes form a well-developed system of vesicles. Opaque particles occur in clusters in the cytoplasm in a higher degree in the secretory cells than in the ciliated cells.The ciliated cells possess cilia which show the usual structural pattern. The cytoplasm of the ciliated cells contains only a few α-cytomembranes as compared with the cytoplasm of the secretory cells. An α-cytomembrane surrounds the nucleus of both ciliated and secretory cells.The assumption that secretory cells can transform into ciliated cells or vice versa cannot be confirmed although in a few cases a single cilium has been found on a secretory cell.
