[Ultrastructure of mucous cells from the oviduct epithelium of the rabbit (Lepus cuniculus). Preliminary study].

Authors studied the ultrastructural features of the mucous cells present in the three segments of the rabbit oviduct in anoestrous. Results showed that only one kind of mucous cell was present in the isthmus while two different kinds of mucous cells were found in the ampulla and infundibulum. The ultrastructural features observed in the isthmic cells correlated well with the histochemical data already described in that segment. However such correlations could not be made between the ampulla and infundibulum. Authors suggest that the ampulla can be considered a transitional segment between isthmus and infundibulum.
