A woman underwent an operation on account of extrauterine (tubal) pregnancy. In course of the operation the surgeon should ligate the branches of the following arteries:

Answer options

1. Uterine and ovarian
2. Uterine and inferior cystic
3. Uterine and superior cystic
4. Inferior cystic and ovarian
5. Superior cystic and ovarian

Explanation

Tubal pregnancy means pregnancy in the uterine tube. The uterine artery divides into descending vaginal branch and ascending branch which supplies the body and fundus of the uterus. The ascending branch bifurcates into ovarian and tubal branches which continue within the broad ligament to supply the medial ends of the ovary and uterine tube and anastomose with the ovarian and tubal branches of the ovarian artery.
