Fig. 57. A non-schematic line drawing of an 11-day ovum

To illustrate the uterolacanar circulation at this developmental stage. In contrast to the cross-sectional views of the other reconstructions on this plate, this is a view of the external aspect of the ovum. Note the vein and spiral arteriole with arteriovenosus capillary anastomoses. The growth and dilatation of the large sinusoid continuous with and derived from such an anastomosis are presumably due to the presence of the adjacent trophoblast. Note that the glands are represented merely as stumps to allow uninterrupted view of the utero-laeunar circulation. See figures 24, :35 and 34. Carnegie 7699. X 50.
