Quizplus · Accepted Answer

The fimbriae are finger-like projections at the end of the fallopian tubes that help to sweep the ovum into the oviduct. They do surround the opening of the oviduct. The internal os is the opening between the cervix and the body of the uterus. The external os is the opening of the cervix into the vagina. The isthmus is the narrowest part of the oviduct. The transverse cervical (cardinal) ligaments hold the cervix in place.
