About which day in a normal human menstrual cycle does rapid secretion of LH (popularly called LH-surge) normally occurs?

2. 14th day
3. 20th day
4. 5th day
| Statement I: | During pregnancy all events of the menstrual cycle stop and there is no menstruation. |
| Statement II: | Cyclic menstruation is an indicator of normal reproductive phase and extends between menarche and menopause. |
| 1. | Statement I is correct; Statement II is correct |
| 2. | Statement I is incorrect; Statement II is correct |
| 3. | Statement I is correct; Statement II is incorrect |
| 4. | Statement I is incorrect; Statement II is incorrect |
| 1. | Day 1 or 2 of menstruation |
| 2. | Day 7; during follicular phase of the menstrual cycle |
| 3. | Day 14; in the middle of a typical menstrual cycle |
| 4. | Day 22; when endometrium is most glandular and vascular. |
| 1. | The follicular phase involves follicle development, estrogen secretion, and endometrial growth, while the luteal phase involves corpus luteum formation and progesterone secretion. |
| 2. | The follicular phase is characterized by corpus luteum formation, while the luteal phase involves follicle development. |
| 3. | Both the follicular and luteal phases involve only estrogen secretion. |
| 4. | The luteal phase occurs before ovulation, and the follicular phase occurs after ovulation. |
In the absence of fertilization, corpus luteum:
| 1. | Stops secreting progesterone but increases the secretion of estrogen |
| 2. | Stops secreting estrogen but increases the secretion of progesterone |
| 3. | Increases the secretion of both progesterone and estrogen |
| 4. | Degenerates |
After ovulation, follicles convert into:
1. Corpus luteum
2. Corpus albicans
3. Corpus cavernosa
4. Corpus callosum
| 1. | Estrogen |
| 2. | Progesterone |
| 3. | Luteinizing hormone (LH) |
| 4. | Follicle-stimulating hormone (FSH) |
