Abstract

In order to characterize morphologically the cervix of ewes to assist in understanding the structure and consequently improve the reproductive efficiency of the species, 22 non-pregnant Santa Inês breed cervix, with a mean age of 3.3 ± 1.1 years and weighing between 28 and 35 kg were evaluated macro and microscopically. We found a cervical length of 6.2 ± 0.99 cm, thus with 6.11 ± 0.43 circular projections. Microscopically, had a layer of cilindric simple epithelium, followed by a layer of loose connective tissue (1.5 ± 0.27 mm) and a layer of smooth muscle tissue (4.5 ± 1.23 mm) to move. After the mucosal muscle layer, a layer of muscle tissue in the longitudinal direction (7.5 ± 0.63 mm). And finally, there is a serous layer (10 ± 2.15 mm) formed by fibers of loose connective tissue. It follows that the cervix of Santa Inês breed of sheep is surrounded by rings fiber-muscular, with folds of mucous membrane of varying size and ramifications.
