tines. It is a hollow organ and at its ceplialic end bifurcates, 

 forming the so called cornua or Tiorns of the uterus. The horns 

 extend obliquely latero-cephalad nearly to the caudal extremity of 

 the corresponding kidney (Fig. 77). 



§ 762. Tuba Fallopiana — Fallopian tube, Oviductus. — Near the 

 ends, the horns of the uterus become quite small and more or less 

 convoluted. This small part of the horn is called the oviduct or 

 Fallopian tube. It opens directly into the peritoneal cavity, thus 

 putting tile peritoneal cavity in communication with the exterior of 

 the body. The end is somewliat funnel shaped and one edge is 

 applied to the ovary. Quain, II, 470. 



Make an incision in one of the cornua near the beginning of the 

 Fallopian tube and pass a beaded bristle into the uterus, and then 

 along the Fallopian tube throughout its whole extent. This will be 

 facilitated by severing the connections of the tube so that it may be 

 straightened. 



§ 763. Ligamentum uteri. — Grasp a uterine cornu and lift it up. 

 A broad membranous band will appear extending laterad from it. 

 This is the ligamentum latum or broad ligament of the uterus and 

 its horns. Like the mesentery and ligaments of the urocyst, it is 

 simply a duplicature of peritoneum. 



Ligamentum rotundum — Round ligament. — Look through the 

 ligament toward the liglit ; a thickening will appear in it extending 

 from near the middle of the horn caudad to the abdominal wall 

 ventrad of Poupart' s ligament (Fig. 39). This is the round ligament, 

 and may be traced through the abdominal wall. It terminates in 

 the external organs of generation. 



g 764. Obvious Structure. — (A) Serous (peritoneal) coat. (B) Muscular coat. (C) A 

 soft mucous coat. These jjoiuts may be easily demonstrated by cutting out a small piece 

 of the uterus or one of its horns. 



§ 765. Microscopic Structure. — (A) Serous (peritoneal) coat. (B) Muscular (unstriped) 

 coat ; the fibers greatly interlace and are mixed with abundant connective tissue. (C) 

 Mucous coat. See Strieker, A, 606 ; Quain, A, II, 464. 



§ 766. Ovarium — Ovary. — At the cephalic end of each Fallo- 

 pian tube (§ 762) may be seen the ovarp, a yellowish oval body 

 about 1 cm. long and .5 cm. wide. It is supported by an exten- 

 sion of the broad ligament. 



§ 767. Microscopic Structure. — (A) Modified peritoneal coat. (B) Ovarian stroma— 

 connective tissue, blood vessels and nerves, Graafian follicles with the ova. See Striclter; 

 A, 510 ; Quain, A, II, 473.
