Abstract
Histological studies on the cervixes of ewes, goats and cows showed a relatively simple structure. Histochemistry indicated that at estrus the type of mucin present varied slightly between the 3 species. However, in all 3, sulfomucins occurred in cells at those parts of the cervical folds closest to the lumen, while in the cells in the crypts or the secondary indentations mucus was more abundant and stained for sialomucins.
