In the control group (under normal conditions), there are regions of intense cellular activity in specific portions of the germinal epithelium. The germinal epithelium gives the ovary a dull gray color as compared with the shining smoothness of the peritoneum; and the transition between the mesothelium of the peritoneum and the columnar cells which cover the ovary is usually marked by a line around the anterior border of the ovary. The outer epithelium is continuous with the peritoneum (serosa) forming a peritoneal fold (mesovarium) between the anterior border of the ovary with the posterior layer of the broad ligament of the uterus.
