The figure below shows the development of follicles (A, B, C, D). Select the option giving correct identification together with its function?
1. B-Secondary Follicle - secretes progesterone
2. D-Corpus Albicans - Secretes estrogen
3. A-Tertiary follicle - Secretes FSH & LH
4. C-Corpus luteum - Secretes progesterone
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
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
At the birth of the female child, the follicles in her ovaries contain:
(1) Primary oocytes that have been arrested at the S phase of the cell cycle
(2) Primary oocytes that have been arrested at the Prophase I of Meiosis I
(3) Secondary oocytes that have been arrested at the Prophase I of Meiosis I
(4) Secondary oocytes that have been arrested at the Metaphase II of Meiosis II
Oogenesis differs from spermatogenesis in a number of aspects. One of the following is however a similarity between the two
1. Growth phase is prolonged in both of them an starts before birth
2. Both give rise to non-motile gametes
3. Both produce equal number of gametes
4. Both occur inside primary sex organ
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
Each Ovary is connected to the pelvic wall and the uterus by:
1. Peritoneum
2. Adipose tissue
3. Ligaments
4. Areolar tissue
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
Ootid is formed along with
(1) Ovum
(2) Second polar body
(3) Secondary oocyte
(4) Primary oocyte
In oogenesis, when a diploid cell undergoes meiosis, how many ova result?
1. 1
2. 2
3. 3
4. 4
