. Cunningham's Text-book of anatomy. Anatomy. THE OVAKY. 1313 Descent of the Ovary.—Like the testes, the ovaries at first lie in the abdominal cavity, and only later assume a lower position. At birth the ovary lies partly in the abdominal, and partly in the pelvic cavity; soon, however, it takes up a position entirely within the pelvis minor. As in the male a gubernaculum is present in the early stages of development. The ligament of the ovary represents the upper part of the gubernaculum which is developed within the plica testis inferior in the male, and the round ligament of the uterus represents the inferior part, which is formed within the plica inguinalis (see p. 1295). It is a rare abnormality for the ovary, instead of entering the pelvis, to take a course similar to that of the testis, and pass through the inguinal canal into the tissue of the labium majus. Structure of the Ovary.—The ovary is for the most part composed of a connective tissue, called the stroma ovarii, richly supplied by blood-vessels and nerves. The stroma contains very numerous spindle-shaped connective tissue fibres, and some elastic tissue. The surface of the ovary is covered by a layer of epithelium, which is composed of columnar cubical cells, and is continuous with the epithelium of the peritoneum forming the mesovarium. The ovarian epithelium is a persistent portion of the germinal epithelium of the embryo which covers the genital ridges, and from which the ova and other cells of the Graafian follicles are derived. The position in which it be- comes continuous with the peritoneum can usually be distinguished as a fine white line near the hilus of the ovary.
