The ovaries, Ovaria, lie in the plane of the superior pelvic 

 aperture, enveloped in the posterior layer of the broad ligament of the 

 uterus; they are of an oval form ; each has an outer obtuse extremity, 

 and an inner end, connected to the uterus by the proper ligament of 

 the ovary, Liyamentwn ovaril propr him, an upper and a lower surface, 

 and an anterior and posterior border. Before menstruation has begun 

 the surface of the ovary is smooth and even, but in later years, after 

 repeated menstruations, it becomes more uneven and is marked by pits 

 and scars. The ovaries are not completely invested by peritoneum, the 

 anterior borders remaining free, and here the bloodvessels enter and leave 

 - lltlus ovaril. The proper fibrous covering is called the Tunica propria 

 s. uUnuj/nca, which is perforated by the bloodvessels at the hilus. 



The Rtroma ovaril is abundantly supplied with bloodvessels and 

 consists of spindle-shaped cells with a small amount of ordinary connective 

 tissue; in the stroma are a great number of closely set vesicles of various 

 sizes, the Graafian follicles. Each larger follicle is surrounded by a 

 dense connective tissue covering, the Theca fottlcidl ; then follows a structurless 

 layer with pavement epithelium, the so called Membrana yranulosa. The 

 cavity contains a light yellow fluid, the Liquor follicull. In one part of 

 the Graafian follicle the epithelial cells are collected into a mass, 

 the J)lscus oopliorus s. proligerus, in the center of which the ovum is 

 imbedded.
