{Which of the following statements is most correct about ovulation
{Which of these statements about environmentally derived abnormal development is incorrect:

+ ovulation results in the release of only an egg (oocyte)
- bacterial and viral infections can affect development
- ovulation results from an increase in body temperature
+ a specific environmental insult will result in a specific abnormal development outcome
- zygote, conceptus, blastocyst
- the first trimester is the most sensitive period to environmental insults
- polar bodies, zygote, conceptus, blastocyst
- some prescription drugs can lead to abnormal development outcomes
||The '''oocyte''' is present before fertilization, the '''conceptus''' refers to all the products of fertilization and is not a developmental stage, '''polar bodies''' are small exclusion bodies enclosing the excess DNA from oocyte meiosis. I did not discuss in detail '''blastomeres'''  a term often used to describe the first cells formed from zygote mitosis.
- rubella virus infection during pregnancy has serious abnormal development outcomes
 
||While we know that "specific environmental insults" can be associated with defects in specific systems, there are many other variables (time, dose, maternal status, synergistic and antagonistic factors, other) which can affect the final developmental outcome.

1 I already really know all I need to know about embryology.

true
false

2 Which of the following statements is most correct about the human menstrual cycle.

The menstrual cycle in all women is a 28 day reproductive cycle
Ovulation always occurs at the midpoint of the menstrual cycle
The menstrual cycle's main function is to regularly replace the lining of the uterus
A high body temperature indicates ovulation is occurring
The menstrual cycle is an endocrine cycle regulating reproductive physiological changes

3 Most pregnancies can be detected by pregnancy tests soon after fertilization.

true
false

4 The most correct sequence of early development following fertilization is:

zygote, blastomeres, morula, blastocyst
oocyte, zygote, morula, blastocyst
zygote, conceptus, blastocyst
polar bodies, zygote, conceptus, blastocyst

5 Which of these statements about environmentally derived abnormal development is incorrect:

bacterial and viral infections can affect development
a specific environmental insult will result in a specific abnormal development outcome
the first trimester is the most sensitive period to environmental insults
some prescription drugs can lead to abnormal development outcomes
rubella virus infection during pregnancy has serious abnormal development outcomes
