Excerpt from Histology of the Oviduct of the HenThat part Of the oviduct lying between the funnel and the isthmus is ordinarily designated as the' 'albumen secreting por tion. While there is good reason to believe that the secretion of albumen is not confined to this region alone, nevertheless it is here that the major portion of this substance is formed.In the active oviduct of a Barred Plymouth Rock hen the albumen portion measures, on the average, nearly 42 cm. In length, or more than half the total length of the oviduct.410 maine agricultural experiment station. 1912.As shown in figure 454, the longitudinal ridges are very high and broad in this part of the oviduct. A better idea of the development of these ridges can be obtained from figure 462. This figure is drawn with the same magnification as figures 457, 458, 468 and 469. It is seen at once that these ridges are much higher and broader here than in any other part of the oviduct. The major portion of this increase in the size Of the ridges is due to the greater development Of the tubular glands. These glands form a distinct tissue layer between the inner layer of connective tissue and the epithelium.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
