These structures are the most common location of Walthard nests. A serous carcinoma called STIC that arises in the stem-like peg cells of these structures may be the true origin of high-grade serous carcinomas of [emphasize] another organ. Interaction with these structures’ epithelium capacitates the CatSper channels of certain rheotactic cells, allowing them to move up these structures’ temperature gradient. The documentary (10[1])The Bleeding Edge highlights the failures of the deprecated Essure procedure, which occluded these structures by inserting (10[1])metal coils into them. (-5[1])A contrast (-5[1])leak during an HSG indicates these structures’ patency. Occlusions of these structures, like those caused by a (10[1])hydrosalpinx (-5[1])or endometriosis, (10[3]-5[1])account (-5[1])for 20 percent (10[2])of female infertility (10[3])cases. (-5[1])For 10 points, (10[1])finger-like (-5[1])projections called fimbriae terminate what paired structures (10[1])that carry eggs (10[1])from the (0[1])ovaries to the uterus? ■END■ (10[6])
