secrete the plug of mucus which commonly occupies the os uteri 

 at the time of birth. 



The Wolffian body. In the female, outgrowths from the 

 anterior Wolffian tubules into the ovary occur, similar to those 

 which in the male give rise to the vasa efferentia ; but they do 

 not give rise to any adult structure. 



A number of the Wolffian tubules of the anterior end of the 

 Wolffian body persist throughout life, forming the structure 

 known as the parovarium (Pig. 249, a), sometimes called the 



Fie. 249. — The adult Ovary, Parovarium, and Fallopian tube. From Quain 

 ' Anatomy.' (After Kobelt.) 



a, a, parovarium, epoophoron, or organ of Rosenmilller ; formed from the anterior end 

 of the Wolffian body. 6, remains of some of the anterior "Wolffian tubules, sometimes 

 forming hydatids, c, the longitudinal duct of the parovarium, formed from the 

 anterior end of the Wolffian duct, d, rudimentary Wolffian tubules, f, atrophieil 

 remains of the Wolffian duct, or duct of Graertner. /, the terminal bulb or hydatid, /i. 

 Fallopian tube, i", hydatid attached to the end of the Fallopian tube. I, ovary. 



epoophoron or organ of Rosenmilller ; a series of transverse 

 tubes which run, with a somewhat tortuous course, in the fold of 

 peritoneum between the ovary and the Fallopian tube, and are 

 connected with the anterior end of the ovary. 



A small portion of the hinder part of the Wolffian body may 

 persist as a rudimentary structure, the paroophoron, lying in the 

 peritoneum opposite the hinder end of the ovary. 



The Wolffian duct persists, in front, as the longitudinal 

 duct of the parovarium (Pig. 249, c), into which the transverse 

 tubules, a, open, and which corresponds to the epididymis of the 

 male. The hinder jiart of the Wolffian duct usually disappears, 

 but it may persist along a greater or less portion of its length as
