CHANGES IN NON-PREGNANT UTERUS 71 



with the posterior layer of the broad ligament of the uterus. In 

 connection with each ovary is a % Fallopian tube or oviduct, which 

 opens into the peritoneal cavity about an inch from the ovary. 1 

 Surrounding the orifice is a fringe of irregular processes or fimbriae, 

 which, when expanded, assist in directing the ovum in its passage 

 into the tube. The tubes are about four inches long, and terminate 

 at the superior angles of the uterus, with the cavity of which they

 towards the ovaries, and do not open outwards as represented in the

are in continuation. They are surrounded by an external serous 

 coat derived from the peritoneum, a muscular coat containing both 

 longitudinal and circular fibres, and an internal mucous membrane, 

 which is highly vascular and is lined within by a ciliated epithelium. 



1 A vestigial structure lying transversely between the ovary and the 

 Fallopian tube on either side is called the parovariurn or epoophoron, or 

 organ of Rosenmiiller, or sometimes the duct of Gartner. It consists of a 

 few scattered tubules, with no aperture. It is the homologue of the epididyruis 

 of the male. Vestiges of a structure corresponding to the organ of Giraldes are 

 also sometimes found in the vicinity of the parovarium, but nearer to the 

 uterus. These have been called the paroophoron.
