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 |
