A.  aComparative morphology and mucus histochemistry of the ruminant cervixbdifferences between crypt and surface epithelium.h[electronic resource]  c1979  aAbstract: 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. The epithelium of the cervix of ovariectomized ewes contained only a small amount of mucus, which stained for sulfomucin. Treatment with estradiol benzoate for 3 days produced large amounts of mucus in the cells and this stained as sialomucin. It is suggested that at estrus, cells in the crypts of the cervix react as though they are more responsive to estrogen and this influences the movement of spermatozoa.  aCows  aGoats  aReproduction  aSheep  aSpermatozoa  aBioquímica  aFisiologia  aHistologia  aReprodução  aRuminante  aUterine cervix1 aADAMS, N.
