The ovary is about 4 cm. (1 1/2 in.) long, 2 cm. (4/5 in.) wide, and 1 cm. (2/5 in.) thick. It is connected with the posterior surface of the broad ligament by a very short mesentery, the mesovarium. It is through this that the ovarian vessels pass. It has two ligaments, one, the suspensory or infundibulopelvic ligament, is a fold of peritoneum going up to the side of the pelvis above and contains the ovarian vessels; the other, the utero-ovarian ligament, going in the broad ligament to enter the uterus just below and behind the Fallopian tube. The ovary lies longitudinally or obliquely against the outer wall of the pelvis with the ureter just behind and below its posterior edge. From its upper end proceeds the suspensory or infundibulopelvic ligament and from its lower end the utero-ovarian ligament. The normal Graafian follicles and corpus luteum should not be mistaken for pathological cysts. The Fallopian tube surrounds the upper end of the ovary and its fimbriated extremity clings to its surface (Fig. 459).

Fallopian Tubes

The Fallopian tube is about 11 cm. (4 1/2 in.) long and runs in the broad ligament along its top or free edge from the uterus to the ovary. Its inner portion between the proximal end of the ovary and uterus is straight and smaller in diameter than the rest and is called the isthmus. Its lumen is about 3 mm. (1/8 in.). The part beyond, or ampulla, curves around the ovary from above downward and is larger than the isthmus and has a lumen of about 8 mm. (1/3 in.). The size of the abdominal opening of the Fallopian tube is about 2 mm. or 1/12 in. The part of the broad ligament between the tube and mesovarium is called the mesosalpinx.
