Each ovary is connected to the pelvic wall and the uterus by:

1.	Peritoneum	2.	Adipose tissue
3.	Ligaments	4.	Areolar tissue

2.

What happens to the majority of the follicles during the phase from birth to puberty?

1.	They get invested by multiple layers of granulosa cells
2.	They enlarge in size and then get dormant
3.	They undergo atresia or degeneration
4.	They cluster together at one end of the ovary

3.

The birth canal is formed by:
1. Vagina alone
2. Vagina and the cervix
3. Vagina, cervix and uterus
4. Vagina, cervix, uterus and oviducts

4.

The final mature follicle is called:

1.	Primordial follicle	2.	Primary follicle
3.	Vesicular follicle	4.	Graafian follicle

5.

Consider the following two statements:

I:	The hymen is often torn during the first coitus.
II:	The presence or absence of hymen is a reliable indicator of virginity.

Of the two statements:
1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct but II is incorrect.
4. Both I and II are incorrect.

6.

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

7.

Identify the part that helps in the collection of the ovum after ovulation:

1.	4	2.	5
3.	6	4.	7

8.

What causes the onset of puberty in males?

1.	Increase in secretion of testosterone by the testis
2.	Decrease in the secretion of testosterone by the testis
3.	Increase in secretion of GnRH by the hypothalamus
4.	Decrease in the secretion of GnRH by the hypothalamus

9.

The correct sequence of mammalian mammary gland ducts beginning from the alveoli would be:

1.	Mammary tubules → Mammary ducts → Mammary ampulla → Lactiferous ducts
2.	Lactiferous ducts → Mammary ducts → Mammary ampulla → Mammary tubules
3.	Lactiferous ducts → Mammary ampulla → Mammary ducts → Mammary tubules
4.	Mammary tubules → Mammary ampulla → Mammary ducts → Lactiferous ducts

10.

The second polar body is formed as a result of:
1. Reductional division in primary oocyte
2. Reductional division in secondary oocyte
3. Equational division in secondary oocyte
4. Equational division in primary oocyte

11.

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

12.

Between childhood and puberty, the ovaries will have follicles containing:

1.	Primary oocyte	2.	Secondary oocyte
3.	Ootid	4.	Ovum

13.

Oogenesis is initiated:

1.	During the fetal life	2.	Just before birth
3.	Just after birth	4.	At puberty

14.

What is released at ovulation?

1.	Primary oocyte arrested at meiosis I
2.	Primary oocyte arrested at meiosis II
3.	Secondary oocyte arrested at meiosis I
4.	Secondary oocyte arrested at meiosis II

15.

In the beginning, the newly formed secondary follicles contain:

1.	Primary oocyte	2.	Secondary oocyte
3.	Ootid	4.	Mature ovum

16.

The cavity of a tertiary follicle is called as:

1.	Antrum	2.	Cumulus
3.	Vitelline space	4.	Sinusoid

17.

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

18.

The cessation of menstrual cycles is called as:

1.	Menarche	2.	Thelarche
3.	Pubarche	4.	Menopause

19.

Zona pellucida is a membrane surrounding:

1.	Secondary oocyte	2.	Secondary follicle
3.	Corona Radiata	4.	Trophoblast cells

20.

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

21.

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
