Q. No.At the birth of the female child, the follicles in her ovaries contain:
| 1. | Primary oocytes that have been arrested at the S phase of the cell cycle |
| 2. | Primary oocytes that have been arrested at the Prophase I of Meiosis I |
| 3. | Secondary oocytes that have been arrested at the Prophase I of Meiosis I |
| 4. | Secondary oocytes that have been arrested at the Metaphase II of Meiosis II |
The diagram represents the tertiary follicle. Identify the correct matched-pair :
| 1. | Secondary oocyte arrested at Meiosis I | ||
| 2. | Zona pellucida mode of glycoprotein | ||
| 3. | Trophoblast cells | 4. | Theca internal |
| 5. | Ovarian cortex | 6. | Antrum |
| 7. | Cumulus oophorus | 8. | Corona Radiata |
| 1. | 1,2,4,6,7 | 3. | 2,3,5,7,8 |
| 2. | 2,4,6,7 | 4. | 1,2,3,4,6,7 |
A polar body, during oogenesis, is formed:
| I: | before fertilization. |
| II: | after fertilization. |
| 1. | Only I | 2. | Only II |
| 3. | Neither I nor II | 4. | Both I and II |
In humans, the process of spermatogenesis in males and oogenesis in females are similar in:
| 1. | Age at which the processes begin |
| 2. | The number of resultant haploid cells |
| 3. | Cytokinesis |
| 4. | Occurring in respective primary sex organs |
An oocyte is released from the ovary under the influence of LH :
| 1. | after completing meiosis and before the polar bodies are released |
| 2. | after completing meiosis I and before the release of the polar body |
| 3. | after completing meiosis |
| 4. | after completing meiosis I and after the release of the polar body |
What is present in the follicles in the ovary of a girl at birth?
| 1. | primary oocytes | 2. | secondary oocytes |
| 3. | oogonia | 4. | ova |
A maturing ovarian follicle consisting of an oocyte surrounded by two or more layers of tall, supporting granulosa cells but lacking an antrum is:
| 1. | Primordial follicle | 2. | Primary follicle |
| 3. | Secondary follicle | 4. | Graafian follicle |
At what stage of the follicular development does the primary oocyte complete its first meiotic division?
| 1. | Primary follicle | 2. | Secondary follicle |
| 3. | Tertiary follicle | 4. | Graafian follicle |
The number of mature ova produced by a young, healthy, nonpregnant adult woman each year would be:
| 1. | 0 | 2. | 6 |
| 3. | 12 | 4. | 24 |
Identify the cell that can be seen in primordial, primary, secondary and tertiary follicle :
| 1. | oogonium | 2. | primary oocyte |
| 3. | secondary oocyte | 4. | ovum |
