Question

The ________ of the uterine tube is between the uterus and the ampulla.
A) isthmus
B) ampulla
C) fimbra
D) os
E) commissure

Accepted Answer

The isthmus of the uterine tube is the narrow portion between the uterus and the ampulla. The ampulla is the wider and more distal portion of the uterine tube. The fimbrae are finger-like projections that extend from the infundibulum and help to capture the ovum. The os is the opening of the cervix that leads into the uterus. A commissure is a junction between two structures.
