Which of the following is the correct matching of the events occurring during menstrual cycle ?
Menstruation - Breakdown of myometrium and ovum not fertilized
Ovulation - LH and FSH attain peak level and sharp fall in the secretion of progesterone
Proliferative phase - Rapid regeneration of myometrium and maturation of Grafian follicle
Development of corpus luteum - Secretory phase and increased secretion of progesterone.
Solution
After ovulation, the ruptured Graafian follicle transforms into the corpus luteum, which secretes progesterone. This hormone is essential for maintaining the uterine lining (endometrium) in preparation for a possible pregnancy. This phase is known as the secretory phase, where progesterone levels rise, leading to the thickening and secretion from the endometrial glands.
