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.
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
