The germinal area alone is made up of three layers of cells (Fig. 10-i), the rest of the upper part of the oosperm being lined with epiblast and hypoblast, while the lower zone of the yelk- sac consists of epiblast only. Simple, non-vascular villi, serving to attach the embryo to the uterine walls, usually project from the epiblast of the subzonal membrane. In the rabbit they do not occur every- where, but only in that region of the epiblast beneath which the mesoblast does not extend, with the exception of a patch which soon appears and demarkates the site of the future placenta. The extension of the mesoblast takes place in every direction from the embryo except directly around the head; but the two. an advanced itase of th JU blood-veflwfi; e, yelk-sac and ite stalk of the umbilical cord i membrane ; r, space c ; 9t, sinus termlnalis Is. ibranes at the staKe of I showing from behind t'j area vosculoaa, the 'Mast; M. blastoderm, nesenterio or vitelline ture placenta; , si- ts membranes, im is inclosed another very -sac) is 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 Mills, Wesley, 1847-1915.
