Which among the following is the commonest site of feilisation in uterine tubes?
Correct Answer: Ampulla
Description: The uterine tubes, or oviducts, or Fallopian tubes are two muscular tubes with considerable mobility, each measuring about 12 cm in length. Each has a funnel-shaped end, the infundibulum, opening into the peritoneal cavity next to the ovary and with a fringe of finger like extensions called fimbriae. The sequence of regions along each tube is as follows: Infundibulum, Ampulla, the longest and expanded area where feilization normally occurs, Isthmus, a more narrow region nearer the uterus, and Uterine or intramural pa, which passes through the wall of the uterus and opens into the interior of this organ.
