| 1. | Diapause | 2. | Ovulation |
| 3. | Menopause | 4. | Menarche |
| A. | The reductive division for the human female gametogenesis starts earlier than that of the male gametogenesis. |
| B. | The gap between the first meiotic division and the second meiotic division is much shorter for males compared to females. |
| C. | The first polar body is associated with the formation of the primary oocyte. |
| D. | Luteinizing Hormone (LH) surge leads to disintegration of the endometrium and onset of menstrual bleeding. |
| Statement I: | Degeneration of corpus luteum in the absence of fertilization is the cause for disintegration of endometrium. |
| Statement II: | Cyclic menstruation indicates normal reproductive phase in human females and extends between menarche and menopause. |
Match the items given in Column-I with those in Column-II and select the correct option given below:
| Column-I | Column-II | ||
| (a) | Proliferative Phase | (i) | Breakdown of the endometrial lining |
| (b) | Secretory Phase | (ii) | Follicular Phase |
| (c) | Menstruation | (iii) | Luteal Phase |
| Options: | (a) | (b) | (c) |
| 1. | (iii) | (ii) | (i) |
| 2. | (i) | (iii) | (ii) |
| 3. | (ii) | (iii) | (i) |
| 4. | (iii) | (i) | (ii) |
| 1. | LH and FSH trigger ovulation in ovary. |
| 2. | LH and FSH decrease gradually during the follicular phase. |
| 3. | LH triggers the secretion of androgens from the Leydig cells. |
| 4. | FSH stimulates the sertoli cells which help in spermiogenesis |
Which one of the following is the correct match of the events occurring during the menstrual cycle?
| 1. | Ovulation - LH and FSH attain peak level and sharp fall in the secretion of progesterone |
| 2. | Proliferative phase - Rapid regeneration of myometrium and maturation of Graafian follicle |
| 3. | Development of corpus luteum - Secretory phase and increased secretion of progesterone |
| 4. | Menstruation - Breakdown of myometrium and ovum not fertilized |
