UROGENITAL SYSTEM. 



From the uterus the tube runs at first horizontally outward 

 toward the lower pole of the ovary, then ascends on the inner 

 side of the anterior border to the upper pole, then arches back- 

 ward and descends on the inner surface along the posterior 

 border. The fimbriated end lies against the lower part of the 

 inner surface of the ovary. [1186] 



Structure. There are four coats, from without inward as 

 follows: serous; muscular, longitudinal fibres superficially 

 and circular ones deeper; submucous; and mucous. [1186] 



The epoophoron (parovarium, organ of Rosenmiiller) con- 

 sists of small blind tubules lying in the mesosalpinx be- 

 tween the Fallopian tube and ovary; one (duct of Gart- 

 ner) lies close and parallel to the Fallopian tube and is 

 joined by the others at right angles. The hydatids of Mor- 

 gagni are small pedunculated cystic structures lying near the 

 infundibulum. The paroophoron consists of tubules in the 

 mesosalpinx, but nearer the uterus; it is only easily found in 

 the newborn. [1128] 



Uterus. This is pear-shaped, three inches long and nearly 

 two wide. The upper portion is flattened and divided into the 

 fundus and the body by a line joining the points of junction 

 (lateral angles) of the Fallopian tubes. The fundus is the con- 

 vex upper part. The body is the triangular lower part, with 

 its base upward; its margins (lateral borders) separate two 

 rounded surfaces, anterior and posterior. The lower portion of 

 the uterus, the neck or cervix, is cylindrical, about an inch 

 long and separated from the body by a constriction. It pierces 

 the upper part of the anterior vaginal wall, being thus divided 

 into supra- and infra-vaginal portions, and tapers somewhat. 

 At its lower end is the opening (external os) of the cervical 

 canal, which is directed toward the upper part of the posterior 

 vaginal wall ; this is circular at first but, after childbirth, be- 

 comes a transverse slit. [1187] 



The cavity of the body is a triangular chink ; its base is di- 

 rected upward and extends between the orifices of the Fallo- 



[243]
