Choose the option that shows the correct sequence of various events occurring during the menstrual cycle.
I) Rapid secretion of Luteinizing hormone (LH)
II) Decrease in the level of progesterone and estrogen
III) Release of FSH under the influence of GnRH
IV) Corpus luteum begins to secrete progesterone and estrogen
I) Rapid secretion of Luteinizing hormone (LH)
II) Decrease in the level of progesterone and estrogen
III) Release of FSH under the influence of GnRH
IV) Corpus luteum begins to secrete progesterone and estrogen
Options
- AIII \rightarrow II \rightarrow I \rightarrow IV
- BIII \rightarrow I \rightarrow IV \rightarrow II
- CII \rightarrow I \rightarrow IV \rightarrow III
- DI \rightarrow III \rightarrow II \rightarrow IV
Correct answer
B. III \rightarrow I \rightarrow IV \rightarrow II
Step-by-step solution
The menstrual cycle begins with the follicular phase, where GnRH stimulates the release of FSH (III).
FSH promotes follicular development. As the follicle matures, estrogen levels rise, triggering a rapid secretion of LH, known as the LH surge (I), which causes ovulation.
Following ovulation, the ruptured follicle forms the corpus luteum, which secretes progesterone and estrogen to maintain the endometrium (IV).
In the absence of fertilization, the corpus luteum degenerates, leading to a decrease in the levels of progesterone and estrogen (II), which initiates menstruation.
The correct sequence is III \rightarrow I \rightarrow IV \rightarrow II.
Answer: III \rightarrow I \rightarrow IV \rightarrow II
