1.	Which one of the following is the correct matching of the events occurring during mentrual cycle?A. `{:("(a) Ovulation"," LHand FSH attain peak level"),(," and sharp fall in the secretion"),(," of progesterone"):}`B. `{:("(b) Proliferative"," Rapid regeneration of"),(" phase"," myometrium and"),(," maturation Graafian"),(," follicle"):}`C. `{:("(c) Development of"," Secretory phase and"),(" corpus luteum"," increased secretion of"),(," progesterone"):}`D. `{:("(d) Menstruation"," Breakdown of myometrium"),(," and ovum not fertilised"):}`
Answer» Correct Answer - B (b) In secretory phase during ovulation, the follicle breaks and collapes under the continuous influence of Luteinising Hormone (LH). It begins to enlarge and forms a yellowish structure, called the corpus luteum. The corpus luteum plays an important role in the preparation of the endometrium for the implanatation of the fertilised egg by secreting oestrogens and progesterone.
