coelomic cavity. The support of the testis is the mesorchium and that of the 

 ovary is the mesovarium. However, supports other than those mentioned in 

 the preceding sentence are concerned with the support of the testis and ovary 

 during development. Figures 3A, B and 351C-3 demonstrate an anterior 

 Hgamentous, progonal support for the developing sex gland, whereas caudally 

 there is a posterior, epigonal support continuing posterially to join the inguinal 

 ligament of the mesonephros. In the developing mammal the progonal sup- 

 port merges with the diaphragmatic ligament of the mesonephros. Caudally 

 the inguinal ligament of the mesonephros joins a ligamentous area in the 

 genital swelling, known as the scrotal ligament in the male and the labial 

 ligament in the female. Consult fig. 351C-6 and C-7 for later history. 



b. Reproductive Ducts 



The male reproductive duct (vas deferens. Wolffian duct) lies close to the 

 kidney structures in the retroperitoneal space in most vertebrates other than 

 those mammals with descended testes (see Chap. 1). The male reproductive 

 duct, therefore, assumes a retroperitoneal position and is not suspended ex- 

 tensively within the coelomic cavity. On the other hand, the female repro- 

 ductive duct (oviduct) is a pendant, twisted structure and is supported by 

 a well-developed peritoneal support, the mesotubarium. In mammals, due to 

 the fact that the reproductive ducts tend to join posteriorly, the mesotubarial 

 supports, along the caudal region of the reproductive ducts, aid in dividing 

 the pelvic region of the coelomic cavity into two general regions, viz., a dorsal 

 or rectal recess, and a ventral, urinary recess (fig. 349L, M). 



In the mammals, the mesotubarial support of the Fallopian tube is known 

 as the mesosalpinx. The mesosalpinx is continuous with the broad, shelf-like, 

 lateral support of the uterus, known as the broad ligament. The broad liga- 

 ment is developed from the mesotubarium together with the remains of the 

 mesonephric kidney substance (349L, M). The round ligament of the mam- 

 malian uterus and the ovarian ligament arise from a basic rudiment com- 

 parable to the gubernaculum testis in the male (see figs. 3; 351C-3, C-6, C-7).
