Some important events in the human female reproductive cycle are given below arranged the events in the proper sequenceA-secretion of FSHB-growth of corpus luteumC-growth of the follicle and oogenesisD-ovulationE-sudden increase in the levels of LH
Correct answer: B. ACEDB
- A. ADCEB
- B. ACEDB
- C. BACDE
- D. CADBE
Explanation
The sequence of events in the human female reproductive cycle and match them with the provided options:A-Secretion of FSH:Follicle-Stimulating Hormone (FSH) is released by the anterior pituitary gland. It initiates the growth of follicles in the ovaries and stimulates the maturation of an egg (oocyte) within a follicle.C-Growth of the follicle and oogenesis:After FSH secretion, the selected follicle grows and develops. The oocyte within the follicle undergoes oogenesis, a process of egg cell development. The follicle secretes estrogen as it matures.E-Sudden increase in the levels of LH:A surge in Luteinizing Hormone (LH) triggers ovulation. This surge is a result of positive feedback from rising estrogen levels. LH surge stimulates the release of the mature egg (oocyte) from the ovary, i.e., ovulation.D-Ovulation:Ovulation is the release of a mature egg from the ovary into the fallopian tube. It is triggered by the surge in LH. The released egg is now ready for potential fertilization by a sperm.B-Growth of corpus luteum:After ovulation, the empty follicle transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, a hormone that helps prepare the uterus for potential pregnancy by maintaining the uterine lining.The correct sequence is:B) ACEDB

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
