fourth of the vagina ; behind, the rectum and sacrum ; above, the small intestine ; 

 and, laterally, the sacro-uterine ligaments investing recto-vesical fascia. 



The two lateral or broad ligaments pass from the sides of the uterus to the 

 lateral walls of the pelvis, forming a septum across the pelvis, which divides that 

 cavity into two portions. In the anterior part are contained the bladder, 



Round 

 ligament.

urethra, and vagina ; in the posterior part, the rectum. Between the two layers 

 of each broad ligament are contained (1) the Fallopian tubes superiorly ; (2) the 

 round ligament ; (3) the ovary and its ligament ; (4) the parovarium, or organ 

 of Rosenmuller ; (5) connective tissue ; and (6) unstriped muscular fibre. 

 Between the fimbriated extremity of the tube and the lower attachment of 

 the broad ligament is a concave rounded margin called the infundibulo-pelvic liga- 

 ment (Fig. 752). The upper border is often known as the mesosalpinx. 



The sacro-uterine ligaments pass from the second and third bones of the sacrum, 

 downward and forward, to be attached one on each side of the uterus at the junc- 

 tion of the supravaginal cervix and the body, this point corresponding internally 

 to the position of the os internum. (For the round ligaments, see page 1177.) 



The cavity of the uterus is small in comparison with the size of the organ ; 

 that portion of the cavity which corresponds to the body is triangular, flattened 

 from before backward, so that its walls are closely approximated, and having its 

 base directed upward toward the fundus. At each superior angle is a funnel- 

 shaped cavity, which constitutes the remains of the division of the body of the 

 uterus into two cornua, and at the bottom of each cavity is the minute orifice of 

 the Fallopian tube. At the inferior angle of the uterine cavity is a small con- 

 stricted opening, the internal orifice (ostium internum), which leads into the 

 cavity of the cervix.
