After ovulation, the ruptured Graafian follicle:
Correct answer: D. Is repaired and eventually forms corpus luteum
- A. Becomes part of the epithelial tissue covering the ovary
- B. Passes into the uterine tube
- C. Forms a more mature follicle
- D. Is repaired and eventually forms corpus luteum
Explanation
ovulation, the ruptured Graafian follicle is not repaired but undergoes a transformation into a structure called the corpus luteum. The corpus luteum secretes progesterone and some estrogen, which are necessary for the maintenance of the uterine lining during the second half of the menstrual cycle. If fertilization does not occur, the corpus luteum degenerates, leading to a decrease in progesterone and estrogen levels, which triggers menstruation.
