Preovulatory, Secondary, Primary, Primordial
Graafian, Primary, Small antral, large antral
Primordial, Primary, Secondary, Preovulatory
Primary, Secondary, Preovulatory
None of the above

Gametogenesis Interactive Component

Attempt the Quiz - Gametogenesis 
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Gametogenesis from the lecture and practical.







  

1

During Prophase I of meiosis:

Reduction of the number of chromosomes occurs
random recombination of hereditary material (DNA) occurs
already duplicated DNA is separated
nondisjunction of the chromosomes could occur
All of the above.

2

In meiosis, the composition of chromatid is changed during:

prophase I
metaphase I
anaphase I
anaphase II
prophase II

3

In a dividing cell, the replication of DNA occurs during:

interphase
prophase
metaphase
anaphase
telophase

4

Which of the following would be the most common karyotype for Turner's Syndrome:

44,XX
45,X
44,XY
47,XXY
46,XX

Fertilization Interactive Component

Attempt the Quiz - Fertilization 
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Fertilization from the lecture and practical.







  

1

At fertilisation:

male and female pronuclei complete their meiotic division
male and female pronuclei enter interphase
cyclic AMP (cAMP) is secreted by the zygote to block polyspermy
the zona pellucida is discarded
All of the above.

2

All of the following are essential for successful fertilization except:

capacitation of the sperm
transport of the sperm through the female genital tract
transport of the zygote to the uterine cavity
separation of the sperm from semen
bidirectional movements of gametes in the uterine tube

3

Fertilization commences when a spermatozoon makes contact with an oocyte and ends:

with the intermingling of maternal and paternal chromosomes at metaphase of the first cleavage division
when the spermatozoon is completely taken into the ootid
when the spermatozoa penetrates the zona pellucida
with the formation of the second polar body
all of the above

4

Transport of sperm through the cervix is assisted by all of the following except:

capacitation of the sperm
the time of the female cycle
properties of the cervical mucus
contractile activity of the uterus
pH


{Select the correct options below that refer to the maternal contributions to the zygote:

type="[]"}

+ mitochondria + nucleolus + one centriole - Y chromosome - polar bodies

Y chromosome is a paternal contribution. The polar bodies do not contribute to the zygote, they are extruded and lost after this first cell stage.


Early Cell Division Interactive Component

Attempt the Quiz - Early Cell Division  
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Early Cell Division from the lecture and practical.

Not quite ready yet. Come back again after the practical for this quiz!







  

1

The zona pellucida is present around:

a primary oocyte
a secondary oocyte
the morula
an early blastocyst
all of the above

2

Which of the following is the correct sequence during the first week of development:

zygote, blastocyst, blastomeres, morula
zygote, morula, blastocyst, blastomeres
zygote, blastomeres, morula, blastocyst
zygote, morula, blastomeres, blastocyst
none of the above

3

Which part of the morula is the region with the most rapidly dividing cells:

the inner cell mass
the trophectoderm
the apical polar region
the outer cells
the inner cells

4

Which cellular part of the blastocyst is mainly involved with the zona pellucida "hatching" process:

the inner cell mass
the trophectoderm
the embryoblast
the blastocoel
none of the above

Interactive Component

Attempt the Quiz - Implantation 
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Implantation from the lecture and practical.







  

1

Which of the following is essential for successful implanatation?

a decidual reaction
transport of the blastocyst to the uterine cavity at the right time
removal of the zona pellucida just before attachment of the blastocyst
release of Prostaglandin E2 by the endometrial stroma
all of the above are needed

2

Diagnostic tests for pregnancy are based mainly on:

levels of oestrogens
levels of progesterone
levels of thyroxin
secretion of human chorionic gonadotrophin (hCG)
secretion of human chorionic somatomammotropin (hCS)

3

During implantation of the blastocyst:

usually implants in the posterior wall of the uterus
release substances that cause local changes in the endometrial tissue
attaches itself to the endometrium at its embryonic pole
implantation can occur anywhere within the uterus or uterine tube
all the above are correct

4

Implantation normally takes place in the:

cervical region
two-thirds lateral uterine tube
body of the uterus, most frequently on the anterior wall
body of the uterus, on the posterior wall
peritoneal cavity

Week 2 Interactive Component

Attempt the Quiz - Week 2 
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Week 2 from the lecture and practical.







  

1

The decidua that takes part in the formation of the maternal component of the placenta is:

the decidua basalis
the decidua capsularis
the decidua parietalis
the villous chorion
the smooth chorion

2

The usual site of ectopic pregnancy is the:

abdominal cavity
uterine tube
ovary
cervix of the uterus
external surface of the uterus

3

Which of the following statements is most correct:

A partial hydatidiform mole is a conceptus with only paternal chromosomes.
A complete hydatidiform mole is a conceptus with only paternal chromosomes.
Triploidy is generated by an oocyte not completing meiosis and then fertilised by one sperm.
Hydatidiform moles are easily identified as they do not produce hCG.
Hydatidiform moles cannot be identified by ultrasound and require other diagnostic tests.

4

Which of the following statements about week two (GA week 4) of development are incorrect:

This is the period of implantation into the wall of the uterus.
Pregnancy from blastocyst hatching after this week occur in 50% of births.
Implantation during this week can occur anywhere within the uterus body.
hCG from trophoblast cells enters the maternal blood stream through uterine blood vessels.
The inner cell mass now differentiates into two distinct cellular layers.
