In life, we go through eight periods of development. The Period of development that I personally feel is most important is the prenatal development. Pregnancy is a physical condition in which a woman’s body is nurturing and developing an embryo or fetus. Prenatal development, or gestation, is the process that transforms a zygote into a newborn. Consequently, the process that ends with the birth of a baby involves two sets of experiences: those of the pregnant woman, and those of the developing zygote, embryo, and fetus (Lifespan Development, Boyd, Bee 2015 p.57). During these times are very vital and there every women who is in the process of giving birth to child should learn positive and negative risk factors of conception. The prenatal …show more content…
The unborn child must be protected from and must endure certain teratogens, depending on the lifestyle of the mother, to be successfully born as a healthy baby. For the duration of prenatal development, the unborn offspring may be affected by a multiplicity of teratogens, which are different factors which can have negative effects on the fetus, and can even cause birth defects. While there are countless factors that can affect an unborn child, the most commonly seen teratogens that should be avoided by a pregnant woman including alcohol, drugs, and tobacco. The intake and ingestion of alcohol during pregnancy is the cause of a disorder which is fetal alcohol syndrome. Fetal alcohol syndrome can cause a birth defect which can cause mental and physical disabilities, as well as cardiac defects in the heart for some situations. Some people believe that small amounts of alcohol in moderation can be acceptable, but there are proven facts that show no alcohol should be consumed during any time of pregnancy. Another dangerous teratogen to refrain from is the use of drugs, prescription and illegal. Many kinds of prescription drugs can influence a fetus and can cause physical and
Pam Jenkins is a 36 year-old woman that is 30 weeks into her third pregnancy. Since her pregnancy began, Pam has gained 20 pounds. Although Pam has reduced the amount that she smokes, she continues to smoke 5 cigarettes per day, which may cause some issues with her worry of another preterm birth. Another factor that could also cause complications is her delayed prenatal vitamin use. After logging her dietary intake within a 24 hour period into SuperTracker, I will be making recommendations on how she can alter her diet and lifestyle to ensure that Pam receives the nutrients she needs for herself and for her baby.
With the increased rate of integrating In Vitro Fertilization (IVF), there has been a steep inclination within the associated needs of specifications. Observably, the development of babies using scientific measures was initially formulated and specified for developing the diverse range of development associated with the same (Turriziani, 2014). However, these developments are noted to be creating an adverse impact on the natural course of events and subsequently, resulting with an adverse impact on the natural process of the development of babies. The initial integrations within the system of IVF for developing babies have further been initiated with the effective use of science to develop a healthy baby. Hence, the use of such progressions can be argued as not hampering the ethical needs associated with the same. Conversely, the initial progression within the same and the changes in the use of such practices are identified as unethical, as it has been acting as a threat in the natural course of development of embryos and altering the natural course of events, suspected to be imposing significant influence on infant mortality (Turriziani,
There are many factors that are integrated into the successful development of a child from Prenatal growth into toddlerhood. Teratogens (outside factors) have a great impact on the babies’ inutero development. Some outside factors like second-hand smoke, smog, or fumes from cleaning chemicals can cause negative effects on the child inside the womb. A few major affects from teratogens could result in low birth weight, head circumference, slow physical growth as well as an effect on mental, behavioral and motor skills (Berk, 2003). The environment around the mother provides many of these outside factors affecting the baby’s growth. But the main link to teratogens during the gestation period is most likely the mother. Daniel S. Messinger and the National Institute on Drug Abuse found that 2.8% of pregnant women admitted to using illicit drugs during their pregnancy (1996). Through illicit drug use, tobacco use and alcohol use, the mother disrupts her baby’s growth with possibly permanent damage.
A mother who drinks while she is pregnant stands a high risk of harming their unborn child because the alcohol passes through her blood to her baby, and that can harm the development of the baby’s cells. This is most likely to harm the baby’s brain and spinal cord. Many of the common effects of a child suffering from fetal alcohol spectrum disorder (FASD) is: distinctive facial features, growth problems making them smaller than the average child, and learning and behavior problems.
The Centers for Disease Control and Prevention suggestion that a pregnant woman should not drink alcohol during pregnancy (Advisory on alcohol use in pregnancy 2005) has been widely criticized as being unnecessarily paternalistic, but the CDC goes further into explaining that, “Alcohol consumed during pregnancy increases the risk of alcohol related birth defects, including growth deficiencies, facial abnormalities, central nervous system impairment, behavioral disorders, and impaired intellectual development” (Advisory on alcohol use in pregnancy
Childbirth is nothing short of a miracle. The placenta—the organ connecting a developing fetus to the uterine wall and allowing for waste elimination, nutrient uptake and gas exchange via the mother's blood supply—filters most harmful substances that threaten an embryo, though some may still pass on to the fetus. These harmful substances, called “teratogens,” range from environmental chemicals to the passing of maternal diseases, and can negatively impact the normal developmental cycle of a fetus. The title “teratogen,” however, effectually refers to any substance or chemical exposure with the potential to cause birth defects in prenatal development. Exposure to teratogens can result in a broad spectrum of physiological and psychological issues in later life, including malformations of the body. (Malformations resulting from exposure to one of the most common teratogens—alcohol—can be observed notoriously in Fetal Alcohol Syndrome, or FAS, where patterns of mental and physical defects develop in association with high levels of alcohol consumption during pregnancy.) Though the toxicity of these teratogens is particularly damaging during the fourth through tenth weeks of gestation, teratogens can harm throughout the span of development in the womb.
Although there are many factors that affect the development of the fetus, research on the specific effects of prenatal maternal stress and the resulting negative outcomes for the development of the fetus will be reviewed. While there is knowledge of these harmful effects in scientific and medical communities, researchers are still in the midst of discovering the results of these negative effects on human development. An overall review of the literature suggests that this topic is still relatively new in research as most of the articles make note that despite the amount of current research studies, there are still many unanswered questions.
In this essay I will be going to consider the lifespan development process and describe the following changes in an infant from content supported in my text. Infants are one of the most amazing transformations I think the world sees. To think we all came from infancy and developed into grown adults who do amazing things everyday. I’ll be talking about the physical change in an infant,as well as the mental changes they experience,and the sensory changes they go through that we all went through and eventually brought us to adulthood.
To put a definition plainly, teratogens are agents responsible for countless birth defects. Research found suggests over eight hundred known teratogens. In this paper, you will find interesting facts based on research, the relationship between teratogens and developmental psychology and some personal views based on the information and research found for this piece.
In 2006, 49% of all pregnancies in the United States were reported unintended on a national survey.1 The highest rate of preventable birth defects and mental retardation is due to alcohol use.2 In this paper, I will further discuss FAS, the potential effects of binge drinking during the embryonic stage of gestation, and what actions need to be taken in order to reduce the incidences of alcohol-related birth defects. Alcohol Consumption During Pregnancy Alcohol is an ethanol containing substance that is a common beverage in many social and private settings. Alcohol is also a teratogen, therefore alcohol consumption and binge drinking potentially pose a substantial risk to the embryo or fetus. In 2013, the Centers for Disease Control conducted a telephone survey of women in the age range of 18-44 years regarding alcohol use.3
1.1 Describe, in-depth, stages of development from conception to birth in groups of 4 weeks i.e. 0-4, 4-8, 8-12...36-40 weeks.
Baby’s take an average of 38-40 weeks to fully develop and prepare for birth. This time period of approximately nine months is broken down into 3 periods in which the baby spends growing from a tiny mass of cells into a functional, healthy, bouncing baby. If all goes smoothly the birth of a baby, including labor time could take between 4-8 hours, sometimes more, sometimes less. There are many factors that can affect the baby’s growth and development, called teratogens, but overall baby will slowly grow and develop until he or she is prepared to enter into the world.
Every woman when pregnant has a 3-5% chance of having a baby born with a birth defect, and these chances increase when the developing fetus/ embryos are exposed to teratogens, whether it’s intentional or unintentional (Bethesda (MD), 2006). Teratogens can cause severe birth defects, malformations, or terminate the pregnancy altogether (Jancárková, & Gregor, 2000). The placenta is known as an effective barrier from any detrimental pathogen that can potentially hurt the fetus. The timing of exposure of any teratogen is critical to the impact of prenatal development (Bethesda (MD), 2006). The most vulnerable time of the fetus for severe damage is during early pregnancy when all the major organ and central nervous system (CNS) are developing. Miscarriages have an important role in keeping a pregnancy from evolving when there is something serious going on with the developing fetus/embryo. Miscarriages are more common than we think and are the most familiar type of pregnancy loss (Bethesda (MD), 2006).
In this report I will be discussing the development issues about prenatal development, and the newborn. Developmental psychology is basically a psychology study that focuses on the cognitive, physical, and social change throughout our life span. In prenatal development we learn about nature and nurture, continuity and stages, and stability and change. Prenatal Development is the process in which babies develop from one single cell after making a baby into an Embryo and later on a fetus . An Embryo is the process of a human organism for about approximately 2 weeks after the fertilization though the second month.
This journal was useful for me because it gave me the background details on why women are opting for delayed motherhood by the age of 30 or 40. Accordingly, I was able to build up my points on how it will affect the health conditions of both baby and mother and also the risk of taking that challenge.
