The division of primary oocyte results in:
1. unequal cells a smaller haploid secondary oocyte and a larger diploid polar body
2. unequal cells a larger haploid secondary oocyte and a smaller haploid polar body
3. unequal cells a smaller diploid secondary oocyte and a larger haploid polar body
4. equal cells - a haploid secondary oocyte and a haploid polar body
How do ovulated oocytes get into the uterus?
| 1. | Because ovaries are within the uterus, the ovulated egg is already within the uterus. |
| 2. | Cilia within an oviduct create currents that sweep the egg toward the uterus. |
| 3. | The oocyte actively swims through the oviduct, using its flagellum. |
| 4. | Fimbriae sweep over the oviduct. |
The primary oocyte completes its first meiotic division within the:
1. Primary follicle
2. Secondary follicle
3. Tertiary follicle
4. Graafian follicle
The developing oocyte divides and releases the first polar body in :
1. Primary follicle
2. Secondary follicle
3. Tertiary follicle
4. Graffian follicle
Refer to the given figure and choose the correct option regarding its parts labelled as A-F.
1. B-Graafian follicle, F-Corpus luteum
2. C-Graafian follicle, A-Ovum
3. B-Primary follicle, C-Tertiary follicle showing antrum
4. E-Corpus callosum, D-Antrum cavity
Assertion : Fallopian funnel of oviduct is with finger-like fimbriae.
Reason : Graafian follicle of ovary is with secondary oocyte hanging in cavity called antrum.
- If both the assertion and the reason are true and the reason is a correct explanation of the assertion
- If both the assertion and reason are true but the reason is not a correct explanation of the assertion
- If the assertion is true but the reason is false
- If both the assertion and reason are false
Oogenesis starts at
| 1. | Embryonic Development stage |
| 2. | At the time, when four million oogonia are formed in female foetus |
| 3. | At the time of birth |
| 4. | More than one option |
Arrested stage called Primary oocyte is formed
| 1. | During foetal Growth | 2. | At the time of birth |
| 3. | At Puberty | 4. | At Menarche |
Primary follicles are formed
| 1. | During foetal Growth | 2. | At the time of birth |
| 3. | At Puberty | 4. | At Menarche |
At puberty, how many primary follicles are there in each ovary in a female?
1. 60000-80000
2. 120000-160000
3. 30000-40000
4. 12000
