THE OVARIES 



1401 



The Ovary at Different Ages. The ovary of childhood is smooth and even. The scars 

 of many ruptured Graafian follicles cause this surface of the ovary to become pitted, puckered, 

 fibrous, and uneven in old age. The surface of the ovary is grayish red in color. The corpus 

 luteum of a nonpregnant woman slowly degenerates and disappears. The corpus luteum of 

 an impregnated woman enlarges during pregnancy.

Structure (Figs. 1158, 1159, and 1167). The ovary consists of the cortex and medulla, 

 in the former of which are found the Graafian follicles and their remains and the hilum of the 

 ovary. The cortex consists of stroma and 

 Graafian follicles. Peripherally, the stroma 

 is condensed to form a capsule, the tunica 

 albuginea, which is covered by a layer of 

 cuboidal epithelial cells called the germinal 

 epithelium, and is often referred to as the 

 serous covering of the organ. These cells 

 are sharply marked off by a whitish line, 

 at the hilum of the ovary, from the endo- 

 thelium of the peritoneum. The stroma 

 consists of a delicate white fibrous tissue 

 meshwork, containing many small blood- 

 vessels and groups of large polygonal epi- 

 thelial cells called interstitial ceils. 



In the stroma are found the Graafian 

 follicles (Fig. 1158) and their remains. 

 The follicles are of different sizes; the 

 smallest are beneath the tunica albuginea, 



the medium-sized follicles are found toward 1'. Attached border. 2. Central stroma. 3. Peripheral

 appearance of the surface of the ovary. A 



large follicle consists of a sheath of stroma called the theca folliculi, the inner portion of which 

 is quite vascular. Lining the theca are several layers of granular cells, the zona granulosa. 

 The greater part of the follicle is devoid of cells, but contains a liquid, the liquor folliculi, and the
