The utero-pelvic ligaments (tig. (341) are the expansions of muscular tissue 

 already deseril)ed in connection with the broad litrarnent. They radiate from the 

 fascia over the obturator internus to the sides of the uterus and vairina, and 

 enslieathe the utero-vairinal vessels and nerves. 



The utero-ovarian ligaments (tig. (339), or ligaments of the ovaries, are 

 short rounded cords continunus with the uterine fibres at the superior auL'le of the 

 organ l)ehind the Fallopian tube, and joining externally the inner end and attached 

 l)f)rder of each ovary. These vari<)us ligamentous structures all serve to main- 

 tain the normal ])Osition of the uterus. In addition, the utero-ovarian ligament 

 aids in the fixation of the ovary, and the round and utero-pelvic ligaments form 

 protective sheaths for vessels and nerves. 



THE FALLOPIAN TUBES OR OVIDUCTS 



The Fallopian tubes (fig. 639) represent the upper extremities of the ^rtillerian 

 ducts, and may ])rol)ably be regarded as cornua uteri both in structure and mor- 

 phology. They are two trumpet-shaped tubes structurally continuous with the

superior angles of the uterus, and running between the two layers of the broad 

 ligaments to become closely connected with the ovaries, partly by direct attachment, 

 ])artly by a peculiar contiguity. Each duct opens internally into the uterine cavity, 

 and its external orifice establishes a continuity between the tubo-ovarian mucous 

 membrane and the peritoneum, but under normal circumstances is closely applied 

 to the surface of the ovary, and receives the ova which are detached from the gland, 

 transmitting them to the uterine cavity. It is al)outfour and a half inches (11 cm. ) 

 in length, straight, narrow, and somewhat cord-like at its uterine end for a distance 

 of about an inch and a half; flexuous, and irregularly dilated in the rest of its 

 length as far as its free extremity, where it becomes exi)anded into a truTn])et- 

 shaped mouth, fringed by a circle f)r circles of diverging villous processes or fimbriae, 

 one of which, the fimbria ovarica, or tubo-ovarian ligament, is attached to the 

 outer extremity of the ovary. One or two little cystic ju'dieulated appendages, like 

 the hydatid of Morgagni in the testicle, may also be appen<led to the mouth. The 

 aperture (ostium abdominale) in the middle of this exiiansion is very small, not 

 more than half a line or a line in diameter, but its mucous membrane may be 

 prolonged for some distance along a furrow in the tubo-ovarian ligament. 



The narrow extremity, or isthmus, has a diameter of about an eighth of an inch
