Milk is produced by which cells?
1. | Alveoli | 2. | Lobes |
3. | Tubules | 4. | Nipple |
Milk produced by alveoli is stored in
1. | Lobes | 2. | Lumen |
3. | Duct | 4. | Glandular Tissue |
Mammary glands are not
1. | Paired structure |
2. | Having glandular tissue |
3. | Having defined amount of fat |
4. | Characteristic of all female mammals |
The glandular tissue of each breast is divided into
1. | 10-12 mammary lobes | 2. | 15-20 mammary lobes |
3. | 23-25 mammary lobes | 4. | 25-30 mammary lobes |
Mammary lobe has not
1. | Alveoli | 2. | Mammary tubules |
3. | Lumen | 4. | Lactiferous Duct |
Which of the following sequences is correct?
(1) Lobes- Mammary Duct- Ampulla- Lactiferous Duct
(2) Alveoli- tubules-Lactiferous Duct-Mammary Ducts
(3) Mammary Ducts- Lactiferous Ducts- Ampulla- Nipple
(4) Mammary lobes- lactiferous Duct- Mammary duct- Nipple
Which of the following does not has 46 chromosomes?
1. | Spermatogonia | 2. | Primary Spermatocyte |
3. | Spermatozoa | 4. | Sertoli cells |
Which of the following has 23 chromosomes?
(1) Secondary spermatocyte
(2) Primary spermatocyte
(3) Spermatogonia
(4) Sertoli cells
The spermatids are transformed into spermatozoa by a process is called
(1) Spermiogenesis
(2) Spermiation
(3) Spermatogenesis
(4) Spermatosis
Spermiation is
1. | Release of sperms from seminiferous tubules |
2. | Release of secondary spermatocyte from seminiferous tubules |
3. | Release of spermatids from seminiferous tubules |
4. | Release of spermatogenic from seminiferous tubules |
