Understand the anatomy of the uterine tube, which is divided into four main regions: the infundibulum, ampulla, isthmus, and interstitial part.
Learn the function and structure of the infundibulum. It is the funnel-shaped lateral margin of the uterine tube, closest to the ovary, and contains fingerlike projections called fimbriae that help guide the ovum into the tube.
Differentiate the infundibulum from the ampulla, which is the wider, central portion of the uterine tube where fertilization typically occurs.
Compare the infundibulum to the isthmus, which is the narrow portion of the uterine tube that connects to the uterus.
Recognize that the correct answer to the question is 'infundibulum,' as it specifically refers to the funnel-shaped lateral margin of the uterine tube.
