Q. No.What happens when a sperm enters the cytoplasm of the secondary oocyte?
1. Release of first polar body
2. Completion of meiosis II
3. Degeneration of polar bodies
4. Dissolution of zona pellucida
The ovaries are located:
| 1. | In a sac outside the body | 2. | In the lower abdomen |
| 3. | In the upper abdomen | 4. | In the thorax |
Corpus luteum is:
1. Ruptured Graafian follicle
2. Released ovum surrounded by cells
3. Developing follicle
4. Enzyme-secreting structure in the ovary
LH surge:
| 1. | is a dramatic sudden increase in the levels of LH during the early part of menstrual cycle and is responsible for ovulation |
| 2. | is a dramatic sudden decrease in the levels of LH during the early part of menstrual cycle and is responsible for ovulation |
| 3. | is a dramatic sudden decrease in the levels of LH during the mid-menstrual cycle and is responsible for ovulation |
| 4. | is a dramatic sudden increase in the levels of LH during the mid-menstrual cycle and is responsible for ovulation |
Changes in the ovary and the uterus, during the menstrual cycle, are induced by the changes in the levels of secretion of:
| 1. | Ovarian hormones | 2. | Pituitary hormones |
| 3. | Both | 4. | None |
Zona pellucida is a membrane surrounding:
| 1. | Secondary oocyte | 2. | Secondary follicle |
| 3. | Corona Radiata | 4. | Trophoblast cells |
What ensures that only one sperm can fertilize the ovum?
1. Corona Radiata
2. Ground substance around ovum
3. Zona pellucida
4. Acrosome
Fertilization occurs at:
1. Infundibulum of the fallopian tube
2. Ampullary – isthmic junction of the fallopian tube
3. Fundus of the uterus
4. Body of the uterus
What is the usual number of primary follicles in both ovaries of a female at puberty?
| 1. | 60000 – 80000 | 2. | 120000 – 160000 |
| 3. | 1 million to 2 million | 4. | About 7 million |
