Question 1
The events of the menstrual cycle take place in association with two main sites. Which are they?
The right answer is the one marked above.
The ovary and the uterus. They are not two separate cycles: both run on the same 28 days, driven by the same hormones. The ovary prepares an ovum while the uterus prepares a place for it to settle.
The pituitary gland does send the instructions — FSH and LH — but it is not a site where the cyclic changes themselves occur. The fallopian tube and the vagina are routes rather than sites of change.
