Prenatal Development And Development Of A Fetus

According to, “Teratogens and their effects on Unborn and Nursing Infants,” published by The University of North Texas, there is a list of common teratogens that are known throughout the world and many reasons that lead to a child having chances for these teratogens. According to Kathleen Stassen Berger, writer of, “The Developing Person through Childhood and Adolescence,” she defines behavioral teratogens to be known as agents and conditions that can harm the prenatal brain, impairing the future child’s intellectual and emotional functioning. The teratogen known for behavioral is known to affect the brain in some occasions if damage is affected a lot more so invading the brain and the child intellectuality to function

A teratogen is a substance that acts as a toxin that can cause a birth defect. A teratogen can be a prescribed medication, a street drug, alcohol use, or even a disease present in the mother that can cause an increased risk for the baby to be born with a birth defect. Some teratogens may cause birth defects that are noticed immediately at birth and some you can’t determine for several years. Usually the more and longer the developing fetus is exposed to teratogens the worse the consequences will be.

A common teratogen that causes problems in pregnancy is the use of methamphetamine, a stimulant that affects a person’s central nervous system, by the potential father or mother. Research on methamphetamine abuse among pregnant women is in progress and has been for several years, but the exact effects of prenatal exposure to this drug are still actually limited. It is common for a child of a mother who used meth during pregnancy to have brain development problems. The National Institute on Drug Abuse(NIDA), (2013) informs us that there have been only small samples of pregnant women researched for only using methamphetamine, therefore, the results are limited to knowing that “neurobehavioral problems such

According to the Centers for Disease Control and Prevention (CDC), birth defects results in one of every 33 babies. Teratogens account for 4 out of 5% of birth defects when chemical and drugs are in the system. The use of this or even infections can cause abnormal fetal development.

A teratogen is any agent or factor that can disrupt the development of an embryo or fetus, which may cause a birth defect or malformation. Whether it is a medication, disease or drug, when the mother is exposed the chances of problems arising with the baby increase. Only ten to fourteen days after conception teratogens can affect the fetus. At that stage in the pregnancy the egg has already been fertilized and attached to the uterus. This is known as the embryonic stage where if health isn’t a priority complications can occur. At this point the mother and embryo share a common blood supply therefore anything the mother does affects the embryo. This is also the stage in which most miscarriages occur. There are numerous teratogens but two

Teratogens such as alcohol and tobacco could potentially affect normal fetal developmental causing developmental disorders and diseases.5,6

Teratogens refers to any environmental agent, such as dose, heredity, negative influences and age that can cause damage during the prenatal period (Berk, 2014). Serious defects can occur during the embryonic period where the “ground work is laid for all body structures and organs” (Berk, 2014, p. 63). During the fetal period teratogens can do minimal damage; however, organs such as brain, eyes, ears, teeth and genitals can still be affected (Berk, 2014).

There are some factors that may influence the health and development. Smoking can affect the babies’ oxygen in the womb which could affect the growth and development, low birth weight, high risk of prematurely (birth before week’s gestation), asthma and may lead to cot death. Genetic factors – when the baby has condition, which means that it has been passed down to them by one of their parents. Infections and medical conditions – some babies have medical condition which may affect them during their childhood. This could lead the babies having low self-esteem, feeling distress, not making friends and effect their development. Alcohol – having alcohol during pregnancy can cause Foetal Alcohol Syndrome (FAS). This could lead

Teratogens can harm an embryo. Most will not kill an embryo. However, any large quantity of teratogens like nicotine will

Therefore, planned pregnancy is a huge key factor in preventing birth defects, because often times birth defects develop even before women might know they are pregnant. Because women don’t know they are pregnant, they may consume alcohol, causing harm to their babies. Smoking causes harm to infants before, during, and after pregnancies. Even in the womb nicotine, carbon monoxide, and many other poisons women inhale from cigarettes are carried through their bloodstream. Smoking while pregnant causes many developmental issues including birth defects, lung problems, stunted growth, increase in babies heart rates, low birth weight, or result in stillbirths. However, there are many other agents known to cause these developmental defects. For example, drugs and other medications such as; thalidomide, isotretinoin, valproic acid, methotrexate, and mycophenolate mofetil are also known to cause the same birth defects (Simeone, et al., 2015). Putting healthy supplements, unlike these types of drugs into individuals systems when pregnant can help prevent infant

Review the evidence that prenatal growth and developmental influences relate to health and disease states later in life.

According to dictionary.com a teratogen is “a drug or other substance capable of interfering with the development of a fetus, causing birth defects”. Teratogens are also substances that are found in the environment which are known to cause defects in fetal development. Teratogens are one of the leading causes of death to newborns in the nation. “There are four major factors that depend on the extent of fetal defects and those are the dosage, genetic makeup of the mother and the developing fetus, fetal age, an other negative influences on pregnancy” (Berk, 2012). Some of the common teratogens include alcohol consumption, exposure to radiation, environmental pollution, tobacco and or drug use, and certain prescription and non-

Why it is important in our society to know what teratogen is, and some ways to prevent this birth defect in our society. Teratogen is a agent that disturbs the development of an embryo. Well, what exactly causes these disturbances in the embryo? By taking medicine during pregnancy, medicine prescribe to new mothers can cause abnormality in pregnancy. Although many women take medications during pregnancy, the medicine prescribe can be harmful. A example may be a woman during pregnancy comes across morning sickness; therefore, she may ask her doctor to prescribe medicine to treat her morning sickness. A common medicine to take during the 60's was thalidomide. However, over the years researchers found that thalidomide caused partial absence

There are numerous health concerns when carrying a fetus. Diet and exercise are crucial when pregnant; the mother is now in control of the nutrition that is implemented to the fetus However, it is essential for those who are expecting to maintain their exercise regime before the pregnancy. “The mother’s nutrition can have a strong influence on the development of the fetus” (Santrock, 2016, p.82). When a woman is pregnant; the percentage of vitamins increase to 50 percent more than usual, sufficient vitamins and nutrients can prevent preterm babies. Janice consistently chooses her prenatal chewable tablets and vitamins as an active role in her prenatal care, maintaining a healthy pregnancy. However, there are parental factors other than maternal which can damage the fetus if the father is exposed to harmful chemicals or even drugs. “Men’s exposure to lead, radiation, certain pesticides and petrochemicals may cause abnormalities in sperm that lead to miscarriage or diseases” (Santrock, 2016, p.97).
