Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (C), (A), (D), (B)
The correct sequence of hormones during the menstrual cycle is:
(C) FSH → (A) Estrogen → (D) LH → (B) Progesterone
- FSH (Follicle Stimulating Hormone) – stimulates the growth of ovarian follicles in the ovary during the follicular phase.
- Estrogen – secreted by the growing follicle; it helps in the regeneration of the endometrium and also exerts feedback control to modulate FSH and stimulate LH.
- LH (Luteinizing Hormone) – a surge in LH causes ovulation (release of egg from the mature follicle).
- Progesterone – secreted by the corpus luteum after ovulation during the luteal phase, it prepares the endometrium for possible implantation.
