UTERUS, PLACENTA, AND FALLOPIAN TUBES.* 



I. UTERUS. 

 BY DR. R. CHROBAK. 



THE peritoneum, which forms an extremely delicate membrane 

 investing the uterus, reaches on its anterior surface a little 

 below the constriction corresponding to the os internum, and on 

 the posterior surface as far as to the attachment of the wall of 

 the vagina to the cervix uteri.f Separating from it at these 

 points, it forms the excavatio vesico- and recto-uterina. Ante- 

 riorly as well as posteriorly it is firmly connected with the mus- 

 cular tissue of the uterus by compact connective tissue, and is 

 so attached that the boundary of that portion which covers the 

 anterior surface, and which can only be detached with difficulty, 

 if at all, forms an angle opening upwards, the apex of which is 

 approxirnatively in the centre of the anterior surface of the 

 uterus.J 



Laterally the intimate attachment of the peritoneum to the 

 uterus only extends to about the distance of one centimeter 

 below the Fallopian tube; beyond this point the peritoneal 

 laminae separate from each other in order to permit the blood- 

 vessels, lymphatics, and nerves to gain entrance into the sub- 

 stance of the uterus.
