Which combination of events is characteristic of ovulation in a healthy human menstrual cycle?
- A.A surge of LH, release of a secondary oocyte, and formation of the corpus luteum from the ruptured follicleCorrect answer
- B.A surge of progesterone, release of a primary oocyte, and degeneration of the corpus luteum
- C.A fall in LH, release of an ovum completed through meiosis II, and formation of the corpus albicans
- D.A surge of FSH, release of a zygote, and transformation of the corpus luteum into a follicle
Solution
A mid-cycle surge of LH causes ovulation. The cell released is a secondary oocyte, arrested at metaphase II. After follicular rupture, the remaining follicular tissue forms the corpus luteum.
