Fig. 81. Remnants of the Wolffian Body in the Female

In Fig. 81 are shown the various remnants of the embryonic renal formations which may persist in the adult female. The Müllerian duct, the upper part of which becomes the Fallopian tube, is situated in the Wolffian ridge (Fig. 80). Hence when the ovary and tube migrate to the pelvis, the Wolffian mesentery, which comes to form the meso-salpinx, is also drawn within the pelvis and with it all the Wolffian remnants in the female. A hydatid attached to the meso-salpinx (part of the broad ligament) at the fimbriated extremity of the Fallopian tube (Fig. 81) is situated at the anterior end of the Wolffian duct and represents the most anterior (cephalic) of the Wolffian tubules or perhaps the cephalic end of the Wolffian duct, or even the pro-nephros, although it is improbable that this transient embryonic structure should persist (J. H. Watson). It certainly corresponds to the pro-nephric remnant found in the frog. It may become enlarged or cystic but never to a great extent. The Wolffian duct (Fig. 81) runs towards the body of the uterus in the meso-salpinx ; it reaches the side of the uterus and passing down in the superficial tissue of the cervix and vagina, terminates in the vulval cleft at the outer side of the opening of the vagina near the duct of Bartholin. Only the upper part of the duct (meso-salpingeal part) persists in women. The uterine and vaginal segments disappear. Parts of these may remain ; they constantly do so in the sow. The uterine and vaginal segments, if they persist, get the name of duct of Gartner. The genital tubules, those attached to or connected with the ovary, persist and form the epoophoron, Organ of Eosenmuller, or parovarium (Fig. 81). They frequently become cystic and give rise to large tumours. The renal Wolffian tubules — those which acted as renal structures in the embryo, also persist, sometimes unconnected with the duct. They lie between the ovary and uterus and form the paroophoron (Fig. 81). They too may form cysts. 2. In the Male.
