The maternal genome plays an important role with respect to drug metabolism, resistance to infection, and other processes that affect the conceptus O c. Manifestation of abnormal development depends on duration of exposure and not dose of exposure to a teratogen. O d. Susceptibility to teratogenesis depends on the development stage at the time of exposure O e. Manifestations of abnormal development include death, malformation, growth retardation, and function disorders.

Describe two additional teratogens that are not frequently occurring. Try to find ones that are rare and/or unusual. One you have identified two, then be sure to discuss what are the potential side effects and risks to the developing fetus.
Factors that can cause congenital malformations by affecting an embryo during its periods of rapid growth and development are called teratogens. TRUE or FALSE
List a number of teratogens and how they impact prenatal development. Provide examples such as research experiments done on this.
Which of the following statements are true about teratogens? Select all that apply. 00000 O The greater the exposure, the greater the impact from teratogens. O Illicit drugs are teratogenic; prescription drugs are safe. Teratogenic impact can be greatly reduced by education and minimizing exposure. Major defects from teratogenic exposure will often result in a spontaneous abortion. The most vulnerable time for exposure and an anomaly to occur is between weeks 16 and 32.
Name and describe each of the three stages of prenatal development. Then go on to explain the possible impact of teratogens at each stage. Specifically, look at what structures are most likely to be impacted at each stage.
It is no mystery how harmful a lot of environmental factors can be on a fetus nor is it misunderstood how important proper prenatal care is during pregnancy. Despite this, we have seen that many people do not receive the recommended care and children are still born with birth defects due to preventable teratogens. explain how you could reduce or eliminate these negative consequences.
Which of the following rows correctly identifies the source of placental formation? Select one: a. Fetal Tissues Maternal Tissues Chorion Endometrium b. Fetal Tissues Maternal Tissues Trophoblast Chorion c. Fetal Tissues Maternal Tissues Chorion Corpus luteum d. Fetal Tissues Maternal Tissues Corpus luteum Trophoblast
Identify one disease, one drug, and an environmental hazard that is known to negatively impact prenatal development. Be sure to describe the specific impact of each teratogen.
What kinds of studies and information are required to determine whether a man’s exposure to a potential teratogen can cause birth defects years later? How would such analysis differ if a woman were exposed?
Understanding the causes of infertility can be valuablein developing new birth control methods. Cite a type ofcontraceptive based on each of the following causes ofinfertility:(a) failure to ovulate due to a hormonal imbalance;(b) a large fibroid tumor that disturbs the uterine lining;(c) endometrial tissue blocking uterine tubes;(d) low sperm count (too few sperm per ejaculate).
