| 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. | 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. |
| 1. | It initiates menstruation. |
| 2. | It triggers ovulation and the formation of the corpus luteum. |
| 3. | It decreases the production of estrogen. |
| 4. | It increases the thickness of the endometrial lining. |
After ovulation, follicles convert into:
1. Corpus luteum
2. Corpus albicans
3. Corpus cavernosa
4. Corpus callosum
| 1. | Menstrual cycle starts with ovulatory phase and ends with menstruation. |
| 2. | The menstrual flow occurs due to breakdown of myometrial lining of uterus. |
| 3. | Menstruation only occurs if the released ovum is not fertilized. |
| 4. | Lack of menstruation is always an indication of pregnancy only. |
| A | B | |
| 1. | Follicular / Proliferative | Luteal / Secretory |
| 2. | Follicular / Secretory | Luteal / Proliferative |
| 3. | Luteal / Proliferative | Proliferative / Secretory |
| 4. | Luteal / Secretory | Proliferative / Follicular |
| A. | In non-primate mammals, cyclical changes during reproduction are called oestrus cycle. |
| B. | First menstrual cycle begins at puberty and is called menopause. |
| C. | Lack of menstruation may be indicative of pregnancy. |
| D. | Cyclic menstruation extends between menarche and menopause. |
| 1. | A, C and D only | 2. | A and D only |
| 3. | A and B only | 4. | A, B and C only |
| Statement A: | The ovulatory phase is followed by luteal phase during which the remaining parts of the Graffian follicle transforms into the corpus luteum |
| Statement B: | Cyclic menstruation is an indicator of normal reproductive phase and extends between menarche and menopause |
| Assertion(A): | A pregnant woman cannot concieve again during pregnancy. |
| Reason(R): | Corpus luteum secretes high level of progesterone and estrogen during pregnancy which inhibits the secretion of gonadotropins and thereby prevent ovulation. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
Which part of the ovary in mammals acts as an endocrine gland after ovulation?
| 1. | Graafian follicle | 2. | Stroma |
| 3. | Germinal epithelium | 4. | Vitelline membrane |
