This essay covers information over the course of prenatal development. I will also discuss teratology and hazards to the prenatal development, those such as, caffeine, alcohol, nicotine, cocaine, marijuana, heroin, and opioids. Additionally, I will discuss how maternal factors such as maternal diet and nutrition, maternal age, emotional states and stress, and paternal factors, may influence prenatal development. The course of prenatal development normally initiates with fertilization and ends with birth, lasting 38 to 40 weeks of gestation. It can be separated into three phases: germinal, embryonic, and fetal. The first two weeks after conception the germinal stage of prenatal development takes place. During this stage, a group of cells, The fetus relies on the its mother for nutrition which is why it is important that a mother maintains a healthy diet and nutrition. Mothers who fail to intake the necessary proteins, vitamins, and minerals during pregnancy is subjected to the malformation of their child. Maternal age is as well associated with the unpleasant pregnancy outcomes. For example, in adolescence the mortality rate of an infant is higher than to mothers of older age. When women of age 35 years or older has become pregnant the risk that the child will have Down syndrome increases. Emotional states and stress during pregnancy can have long term consequences such as having a child with emotional or cognitive problems, attention deficit hyperactivity disorder, and language delay. It is concluded that mothers who suffer from depression during pregnancy can be linked to preterm birth, low weight at birth in full-term infant, and an increase risk that depression will develope in the adolescence. Not only does maternal characteristics influence the prenatal development of the offspring but so does the paternal. A father who smokes around the pregnant mother leads to a risk of early pregnancy loss and leukemia may also arise from second hand smoking. The father who is of age 40 or older is at risk of
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.
Neonatal Abstinence Syndrome (NAS) is a group of problems a newborn experiences when exposed to addictive drugs that the mother consumes during pregnancy. NAS is a growing concern in the United States and can have significant adverse effects on newborns. Shortly after birth, the infant can display many physical symptoms of withdrawal. In addition, substance abuse during pregnancy can cause premature birth, low birth weight, seizures, birth defects, Sudden Infant Death Syndrome (SIDS), and possible long-term cognitive and behavioral problems. The 2010 results from the National Survey on Drug Use and Health: Summary of National Findings reported incidence of substance abuse among pregnant women within the United States....
Drug and alcohol use in pregnancy poses a threat to the neonate’s development and the obstetric provider has an obligation to screen for substance use. Substance use in pregnancy can place the developing fetus at risk for in-utero opioid dependence, fetal-alcohol syndrome, preterm labor, and other consequences of maternal alcohol, tobacco, and illicit drug use.(6) Within the past three years La Crosse County has seen a marked increase in the amount of heroin use.(7)
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.
Tobacco use during pregnancy is another environmental influence. The nicotine, carbon monoxide, and many other harmful chemicals mixed together in cigarettes are very harmful to the mother and especially the unborn child. This can cut off the baby’s oxygen supply, increase the risk of
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.
Based on my knowledge about prenatal development and childbirth I expected the women to answer the way they did. Development happens rapidly during the prenatal period, which is the time between conception and birth. Prenatal development is normally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage.
Substance abuse during pregnancy can have a negative force on the health and wellness of not only the fetus, but that of the mother. The harmful effects of medications, alcohol and illegal drugs on an unborn child can be devastating and can have significant consequences to its use. Sometimes the effects can be faced and treated, and other times the outcome is a lifelong challenge. During the prenatal period, it is important that new mothers are informed of the different types of abuse, how they may affect the fetus, and the adverse conditions their child may be faced with before and after birth.
“I brought you into this world, and I can take you out!” A child has most likely heard that phrase at some point in their life. Although, it is not ethical or legal for a mother to “take her kid out of this world”, it does bring up a good point that it was through her body, that the child was born. One of the most important responsibilities in this world is a mother carrying a child in the womb. There are many divine processes that take place during gestation, but there are also many contributing factors from the mother that can affect the developing human. These factors may include what a woman ingests and exposes her embryo or fetus to. Sadly, alcohol use during pregnancy is an ongoing problem that can have detrimental affects on the fetus, including Fetal Alcohol Syndrome (FAS). Choosing to drink alcoholic beverages during pregnancy is a choice, a risky choice. Unfortunately some women don’t even know they are making a risky choice by consuming alcohol because it is in the early stages of pregnancy. It is common for a female to not find out they are pregnant until at least the fifth or sixth week after fertilization. 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.
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.
The early developmental stages of babies is key to starting a good life long learning experience. This is the certain time in which their brains are really trying to make progress and grow. Babies need that love and sense of closeness to obtain a healthy start. Obviously mothers who smoke, drink or do drugs while pregnant can cause serious health problems to their fetus. Also when they are young most of the time these problems persist and do not get any better. This causes children to have the chance to obtain the same lifestyles as of the parents.
Smoking is harmful to the mother, as it is to any individual who smokes, but it is linked to severe health issues for the baby. Problems seen in unborn foetuses include low birth weight, defects and even miscarriage. Problems seen in neonates include sudden infant death syndrome, asthma and childhood obesity. The mother is also at risk of vaginal bleeding and premature labour2.
Development is a never ending cycle in life. Each person begins to develop from conception until passing away. Now, while most people think that development starts after birth that is incorrect. Development starts as soon as the baby is conceived. Everything that a woman carrying a baby does or takes place in will translate into the baby. The baby shares a blood flow with the mother. Drugs, even legal drugs, will go into the mother’s blood stream which will then go into the baby’s blood stream. The “maternal blood flows through the uterine arteries to the spaces housing the placenta, and it returns through the uterine vein to the maternal circulation” (Santrock, 2012, p. 80). This means that anything that enters into the blood stream will also affect the baby. Each type of drug is under a certain category. Psychoactive drugs are drugs that are constantly being studier. According to Santrock (2012), psychoactive drugs are drugs that act on the nervous system to alter states of consciousness, modify perception, and change moods. (p.83). They come in three categories: stimulants, depressants, and hallucinogens. Stimulants include caffeine, cocaine, methamphetamine and nicotine. Some people say that pregnant woman do not know what taking these into their system is doing to their baby. Stimulants are becoming more popular and there effects need to be studied and known. Each stimulant affects the baby in short-term and long-term.
There are two different ways to break down the prenatal time period: by trimester or by periods. The first period is called the germinal period. This time frame consists of the first fourteen days of the baby’s development starting with conception. During these two weeks, the fertilized egg makes it’s way into the uterus for implantation in the lining of the uterus. The next period, the embryonic period starts here. The embryonic period lasts the third through the eighth week of pregnancy. During this time period, according to Kathleen Stassen Burger, Author of The Developing Person: Through Childhood and Adolescence, “…the formless mass of cells becomes a distinct being-not yet recognizably human, but worthy of a new name, embryo” (Burg...
This process is called conception, the female is now officially two weeks pregnant and the fertilized egg is called a zygote. Let’s move on to pregnancy. Pregnancy is a state in which a woman carries a fertilized egg inside her body, it usually lasts up to 40 weeks, and it is divided into three trimesters, each lasting three months. The first month. The embryo is about a third of an inch long. The head, trunk, and the beginnings of the arms and legs have started to develop. By this month, the embryo starts to receive nutrients and releases waste through the umbilical cord and placenta. The heart also starts to beat. The second month. The heart is now pumping and the nervous system, including the brain and the spinal cord begins to develop. The fetus is 1 in 2.5cm now and has developed cartilage skeleton. The arms, legs, facial features and other major organs begin to appear. The third month. The fetus has grown up to 4 in 10cm and weighs a little more than an ounce. The major blood vessels are almost completed and the face starts to show up more. The kidneys and the 4 chambers of the heart are now complete. The fourth month. The fetus is now 4 oz of 112g and can kick and swallow. The
