Arrange the given events of menstrual cycle in correct sequence.(A) D…

The correct answer is Option (2) → (A), (C), (B), (D)

(A) Developing follicle — this comes first. In the follicular phase, FSH makes the primary follicles in the ovary grow.

(C) Mature follicle — this comes second. One follicle becomes the mature Graafian follicle, and it releases the ovum at ovulation.

(B) Developing corpus luteum — this comes third. After ovulation, the remains of the follicle turn into the corpus luteum, which makes progesterone.

(D) Regressing corpus luteum — this comes last. If the ovum is not fertilised, the corpus luteum degenerates, and menstruation follows.

NCERT Extract:
Menstrual Cycle – “… The menstrual phase is followed by the follicular phase. During this phase, the primary follicles in the ovary grow to become a fully mature Graafian follicle and simultaneously the endometrium of uterus regenerates through proliferation.”
Menstrual Cycle – “… The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle transform as the corpus luteum (Figure 2.9).”
Menstrual Cycle – “… In the absence of fertilisation, the corpus luteum degenerates.”
