Which of the Following is True About the Uterine Tubes

Question

Which of the following is true about the uterine tubes?
A) The ampulla is a narrow constricted region.
B) The infundibulum is the expanded region of the uterine tube.
C) The isthmus is the normal site of fertilization.
D) none of the above

Accepted Answer

The infundibulum is the expanded region of the uterine tube and contains finger-like projections called fimbriae that sweep over the ovary during ovulation to capture the released egg. Option A is false because the ampulla is the wider region of the uterine tube. Option C is false because fertilization normally occurs in the ampulla, not the isthmus.
