Ovaries are the primary sex organs in human females because they:
I: | Produce the female gamete. |
II: | Produce the hormone that regulates the development of secondary sexual characters. |
1. | Both I and II | 2. | Only I |
3. | Only II | 4. | None |
Between childhood and puberty, the ovaries will have follicles containing:
1. | Primary oocyte | 2. | Secondary oocyte |
3. | Ootid | 4. | Ovum |
Oogenesis is initiated:
1. | During the fetal life | 2. | Just before birth |
3. | Just after birth | 4. | At puberty |
Corpus luteum is essential for:
1. Release of ovum
2. Development of follicles
3. Maintenance of endometrium
4. Contraction of the myometrium
What is released at ovulation?
1. | Primary oocyte arrested at meiosis I |
2. | Primary oocyte arrested at meiosis II |
3. | Secondary oocyte arrested at meiosis I |
4. | Secondary oocyte arrested at meiosis II |
In the beginning, the newly formed secondary follicles contain:
1. | Primary oocyte | 2. | Secondary oocyte |
3. | Ootid | 4. | Mature ovum |
The correct sequence of male sex accessory ducts beginning from testis would be:
1. | rete testis → vasa efferentia → epididymis → vas deferens |
2. | rete testis → vas deferens → vasa efferentia → epididymis |
3. | vas deferens → vasa efferentia → epididymis → rete testis |
4. | vasa efferentia → vasa deferens → epididymis → rete testis |
Which hormone is mainly secreted by the developing follicles during the proliferative phase of the menstrual cycle?
1. | LH | 2. | FSH |
3. | Progesterone | 4. | Estrogen |
During pregnancy:
1. | All events of menstrual cycle stop and there is no menstruation |
2. | Events of menstrual cycle continue but there is no menstruation |
3. | Events of menstrual cycle continue but there is menstruation only in the first trimester |
4. | All events of menstrual cycle stop and there is menstruation only in the first trimester |
Consider the following two statements:
I: | Not all copulations lead to fertilization and pregnancy |
II: | Fertilization can occur if the ovum and the sperms are simultaneously transported to the fallopian tubes. |
1. Both I and II are correct and II correctly explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct but II is incorrect.
4. I is incorrect but II is correct.
