The cow has the longest and most powerful cervix: it is 3 to 5 inches antero-posteriorly and 2 to 3 inches transversely. Its muscular walls are so rigid, and its circular muscle fibres so contracted that it is exceedingly difficult to dilate the canal mechanically, but it dilates freely under the influence of estrum and parturition. The cervix of the mare is shorter than that of the cow and the walls far thinner and more pliable, rendering its canal readily Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Williams, W.
