Q. No.The correct sequence of mammalian mammary gland ducts beginning from the alveoli would be:
1.
Mammary tubules → Mammary ducts → Mammary ampulla → Lactiferous ducts
2.
Lactiferous ducts → Mammary ducts → Mammary ampulla → Mammary tubules
3.
Lactiferous ducts → Mammary ampulla → Mammary ducts → Mammary tubules
4.
Mammary tubules → Mammary ampulla → Mammary ducts → Lactiferous ducts
The spermatids are transformed into spermatozoa by a process called:
| 1. | Spermiation | 2. | Spermatocytogenesis |
| 3. | Spermiogenesis | 4. | Spermatolysis |
The second polar body is formed as a result of:
1. Reductional division in primary oocyte
2. Reductional division in secondary oocyte
3. Equational division in secondary oocyte
4. Equational division in primary oocyte
Which of the following will carry 46 chromosomes?
| 1. | Sperms | 2. | Spermatids |
| 3. | Secondary spermatocytes | 4. | Primary spermatocytes |
The first menstruation begins at puberty and is called as:
| 1. | Menarche | 2. | Menopause |
| 3. | Thelarche | 4. | Pubarche |
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 |
