Teratogens are substances in the environment that cross the placenta to damage the fetus. Mothers are usually exposed to them during pregnancy. They cause major damage during the embryonic stage. Teratogens also affect the still developing brain. The damage done depends on the amount of dosage taken in toxic substances. They damage unpredictably. There are many different types of teratogens. Medications, recreational drugs, stress and infectious disease are some examples of teratogens. Medications such as antibiotics, thalidomide, anti-seizure drugs, anti-psychotic drugs and antidepressants are very harmful for fetus development. Streptomycin is an antibiotic most commonly used to treat tuberculosis, was linked to causing hearing loss in children. According to about kids’ health website, thalidomide was discovered in the 1960s to treat morning sickness, when taken by pregnant women, it caused total or partial absence of the arms or legs in babies. Furthermore, anti-seizure medication have been linked to delayed development in infancy. Anti-psychotic drugs raise the risk of the baby developing heart problems. Lastly, anti-depressants in the third trimester of pregnancy can cause temporary jitteriness, excessive crying and eating difficulties in newborns. Antibiotics should be avoided during the sensitive stage of fetal development. Mothers should have a very thorough conversation with their physicians on effects of antibiotics, prescribed to them, on their babies. Recreational drugs such as cocaine and methamphetamines are very dangerous for pregnant women. Cocaine is linked to causing miscarriages, growth retardation, and behavior problems. Similarly, methamphetamines are linked to causing miscarriages and growth retardation. Recreational drugs should be avoided at all times during pregnancy. According to Belsky (2012), a huge collection of studies propose…...

...Make sure to eat well and healthy. Many soon to be mothers do not take into consideration their diets and how much of an impact it will have on your baby. The rights foods and increase the development of your fetus, as the wrong ones or lack of nutrients will danger your baby. Alcoholism’s Don’ts: You are strongly urged to avoid the consumption of alcohol, not only because it’s frowned upon by society, but it can cause major damage to your unborn child. Fetal Alcohol Syndrome (FAS) is the result of alcoholism during pregnancy. Your baby can be born with birth defects including abnormalities, halted growth, and retardation. Avoid Teratogens: Teratogens are considered to be “substances such as drugs and pollutants and conditions such as malnutrition and extreme stress”. (Berger, 2010) They increase the risk of prenatal abnormalities. Teratogens include viruses, chemicals, and drugs. They can also be found in household products and cleaners, and with that being said, always read the labeling and avoid inhaling miscellaneous substances. These three activities are the most important of them all, you must keep yourself updated and educated on simple facts of pregnancy. Without performing these activities you are definitely putting yourself and your fetus at risk. Be sure to protect yourself and your baby.

Parental Development

...* ------------------------------------------------- 6. The 3 main types of prenatal development are the zygote, embryo, and fetus. The zygote is the fertilized egg in the womb; it lasts for 2 weeks and begins when the sperm first fertilizes the egg. Soon afterwards, the zygote becomes an embryo. During the embryo stage, the actual human organism is mad and this lasts from the 2nd week to the 2nd month. During the fetus stage, the organism is in its developmental stage. This begins after 9 weeks of pregnancy. A teratogen is an agent that can cause harm to the womb ex. If a pregnant woman is drinking a lot of alcohol, she can harm the fetus because alcohol is a teratogen and she could potentially cause fetal alcohol syndrome.  7. The brain capacity of newborn babies is a lot smaller than that of an older person. That’s why we don’t remember most of our infancy. Once we are born we start to make a neural network that allows us to complete basic functions, like talk, remember, etc. The habituation for the infant cognition is a very simple way of learning. When the babies are exposed to something multiple times, they lose fascination in it. 8. Piaget developed 4 stages of cognitive development that show how humans develop mentally. Stage 1 is the sensorimotor stage. This is the stage that occurs from 0 to 2 years and this is when we start to interact with our senses. The 2nd stage, Preoperational, 2-7 years old, is when language begins but isn’t completely understood and......

...provided in both articles and this can provide a challenge to an analytical process (Krapp & Wilson, 2006). Krapp and Wilson only provide general statements e.g. they state that about 90% births in the U.S. are usually healthy apart from sporadic incidences of congenital problems that may occur among others. Some problems are inherited while others depend on environmental circumstances. This is the nature vs. nurture in child health that is considered to influence the development of a child. (Krapp & Wilson, 2006). Moore and Schneider address various impacts of toxins on fetal development and make reference to experiments done on various animals; “the effect of teratogen was found to be resistant in mice and rats after limb induction using thalidomide, rabbits and hamsters showed variable effects.” Teratogen is any drug, chemical, maternal disease, or exposure that can lead to physical or functional defects in an embryo or fetus when exposed. Those observations are a good illustration of toxin effects but they are too broad and no numeric evidences have been documented (Moore & Schneider, 2006). Different approaches of these nature are however important both to professionals and students as well. While Krapp provides diagrammatical illustrations, it will serve any clinician with an intention to provide visual references to his office n form of display charts. Community health workers make use of this kind of data to make visual aids in rural areas in case of......

Brain Development

...sixth week of pregnancy, an embryo’s brain is able to move in response to stimuli and by week eight the brain connects with the rest of the body. During the fetal stage between 13 and 21 weeks, the neurons are set in place in the brain; this is where they will remain for the rest of the person’s life. Once the neurons are in their final place they began to develop connections to other neurons which is called synapses. At this point, a fetus can be observed having times of activity and time of rest which indicate normal brain development (Boyd & Bee, 2012). A fetus’s environment is inside the mother’s womb; however, outside environmental factors can have an effect on that environment. Teratogens are substances that can cause birth defects and include drugs, alcohol, lead, and viruses. These teratogens can have major effects on the brain. Alcohol use during pregnancy can cause problems with thinking, remembering, and mental retardation. Environmental chemical such as mercury and lead can lead to neurological problems and mental retardation (About Kids Health, 2013). Brain Development in Infancy When a baby is born, most of the neurons that will be used for the rest of a person’s life are present and only a few neurons are created after birth. The neurons that are present at birth lack the necessary connects to other neurons which allow mature brains to function properly (Perry, 2002). Synapses are the connections between neurons. The creation of synapses occurs at a great......

Prenatal Development

...as prostaglandins and the progesterone-estrogen balance can prevent implantation, resulting in embryonic death. During organogenesis, when the molecular, cellular, and morphological structural organization of tissues and organs takes place, the embryo is considered to be most susceptible to structural defects. Animal experiments show that the exact timing of exposure to a teratogen affects the pattern of structural malformations. However, malformations usually occur in more than one organ system because of overlap in the sensitive period of development of different systems. Functional effects and growth retardation, rather than malformations, are considered to be the most likely outcomes of toxic exposures during the fetal period. However, there are exceptions to these generalizations. For example, skeletal abnormalities in mice can be induced during the preimplantation stage. Susceptibility to teratogens or other causes of untoward birth outcomes also depends on species, genetic characteristics, and the history of the mother herself. Examples of species and genetic influences on the effects of a teratogen are that mice and rats were found to be resistant to the induction of limb defects by thalidomide, whereas rabbits and hamsters showed variable effects, and some species of primates were highly sensitive to the teratogenicity of thalidomide. The life history of the mother can also affect outcome. For example, the sensitivity of the fetus to alcohol appears to increase......

Perinatal and Prenatal Environmental Influences

...babies can be profoundly damaged by teratogens during prenatal development. Teratologists estimate that 6% to 10% of birth defects are caused by environmental causes such as toxic chemicals and drugs (Greenberg, Bruess, & Conklin, 2007). A teratogen is any environmental agent that causes damage during the prenatal period of development (Berk, L 2008). The damage inflicted on the fetus depends on numerous factors such as dose, heredity, age and other negative influences. A higher dose of particular teratogens over a period of time has more negative effects. The genetic makeup of the fetus’s mother plays a contributory role in resistance to malformation. Influences such as poor health care and nutrition can increase the amount of damage teratogen’s can cause to the unborn child. Environmental events that may adversely affect the development of a child is still underestimated and not fully understood and negative affects to cognitive development is not immediately observed upon birth. It is crucial during sensitive periods of growth for a mother to abstain from exposure to environmental hazards which have been known to cause irreversible prenatal damage to the physical and cognitive development of the fetus. The embryonic period from three to eight weeks is the time when serious defects are most likely to occur because the foundations for all the body parts are being laid down (Berk, L. 2008). The negative effects of teratogens go beyond immediate physical damage,...

...progesterone-estrogen equalization can avoid implantation, bringing about embryonic demise. Amid organogenesis, when the atomic, cellular, and morphological, structural organization of tissues and organs happens, the embryo is thought to be most defenseless to structural imperfections. Creature examinations demonstrate that the careful timing of presentation to a teratogen influences the example of structural malformations. In any case, malformations happen in more than one organ system due to cover the touchy period of development of diverse systems. Utilitarian impacts and development impediment, instead of malformations, are thought to be a no doubt conclusions of harmful exposures amid the fetal period. Be that as it may, there are exemptions to these speculations. Case in point, skeletal anomalies in mice can be prompted amid the pre-implantation stage. Defenselessness to teratogens or different reasons for problematic conception conclusions likewise relies on upon species, hereditary qualities, and the historical backdrop of the mother herself. Samples of species and hereditary impacts on the impacts of a teratogen are that mice and rats were discovered to be impervious to the actuation of appendage deserts by thalidomide. While rabbits and hamsters demonstrated variable impacts, and a few types of primates were profoundly delicate to the teratogenicity of thalidomide. The life history of the mother can likewise influence result. Case in point, the......

Happy Feet and Disibilities

...it is known that an egg must never be dropped because of the frigid temperature. Although it was unlikely for Mumble to hatch after the drop, he hatches and is livid with his feet. Mumble, in good spirits displays his unconventional talent. Not only was Mumble born with “happy feet” he was also born with the inability to sing. In order for penguins to mate, they must be able to serenade a female penguin. Without this important trait Mumble’s parents as well as the community are left in confusion. Possible causes of disabilities in children similar to Mumble would involve teratogens. “Teratogens are drugs, chemicals, or even infections that can cause abnormal fetal development. There are billions of potential teratogens but only a few agents are proven to have teratogenic effects,” (Pregnancy and Teratogens). Anything caused by an external force would be similar to the cause Mumble’s development. Teratogens can cause learning disabilities such as dyslexia and ADHD. Although it is not too obvious Mumble’s appearance is also different, he has a fluffy outer coat unlike his peers, and has blue eyes, and is smaller in size than the rest of his peers. Mumble’s development is similar to that of a child with ADHD. He is unable to control his “happy feet,” as well as short attention span when told not to sing or dance. Children with ADHD often suffer from not being able to focus, being overactive and not being able to control their behavior. This is displayed when Mumble......

...worker at a health center I would create an effective advertising campaign targeting teens, create a catchy slogan, develop poster and handouts, and also have meetings and fundraisers to bring awareness to the rises of teenage pregnancy and teratogens. Teenage Pregnancy Risks Infants born to teenage mothers are at increased risk for a number of health risks. The risks include the premature baby and low birth weight. Teenage mothers are less likely to gain the required amount of weight during their pregnancy this will cause low birth weight for the baby. Low birth weight is associated with many infant and childhood disorders and a higher rate of infant mortality. Low-birth weight babies are more likely to have organs that are not fully developed; this can result in many complications, brain disorders, respiratory disorders, and intestinal problems. Teen’s moms also are more likely to smoke cigarettes, drink alcohol, or take drugs during pregnancy, which can cause numerous health problems for the baby. A teratogen is an agent, which can cause a birth defect; it could be a prescribed medication, a street drug. Generally these abnormalities occur in the third to eighth weeks of pregnancy, when the major organs are forming. Examples of teratogens include certain chemicals, medications, and infections or other diseases in the mother. Children born to teenage mothers are more likely to experience social, emotional, and other problems. These problems may include the......

...occurs during the ninth week and will last until birth. The body systems and structures that were formed during the embryonic stage continues to develop. The neural tube grows to form the spinal cord and the brain and also the neurons form. The sex organs appear at the third month of gestation. The fetus continues to grow in both length and weight. During the embryonic stage of development, the embryo becomes fragile since the major organs forms at this stage (Yoshinaga, 2010). The teratogens are the biggest threats to the developing embryos. A teratogen refers to any drug, disease or environmental agent that can cause deformities to a developing embryo or fetus. Some teratogens cause a ‘sleeper' effects. A single teratogen can cause a variety of defects in the developing embryo. A serious damage will be done to the embryo it will be exposed to the teratogens for a longer time. Also, same defect or harm can be caused by the same teratogen. The type of deformity caused by this teratogen will depend on the embryonic developmental stage. If the mother ingests alcohol at the time of pregnancy it can lead to fetal alcohol syndrome (Jones, 2011)This syndrome causes a low intelligence and adjustment problems, malformations and microcephaly of the heart, limbs, and face. The risk of fetal alcohol syndrome is highest for alcoholics and binge –drinkers.

...such as aggression or behavioral disinhibition occasionally occur.[5] Long-term use is controversial due to concerns about adverse psychological and physical effects, increased questioning of effectiveness and because benzodiazepines are prone to cause tolerance, physical dependence, and, upon cessation of use after long term use, a withdrawal syndrome.[6][7] Due to adverse effects associated with the long-term use of benzodiazepines, withdrawal from benzodiazepines, in general, leads to improved physical and mental health.[8][9] The elderly are at an increased risk of suffering from both short- and long-term adverse effects.[8][10] There is controversy concerning the safety of benzodiazepines in pregnancy. While they are not major teratogens, uncertainty remains as to whether they cause cleft palate in a small number of babies and whether neurobehavioural effects occur as a result of prenatal exposure;[11] they are known to cause withdrawal symptoms in the newborn. Benzodiazepines can be taken in overdoses and can cause dangerous deep unconsciousness. However, they are much less toxic than their predecessors, the barbiturates, and death rarely results when a benzodiazepine is the only drug taken. When combined with other central nervous system depressants such as alcohol and opiates, the potential for toxicity increases.[12] Benzodiazepines are commonly misused and taken in combination with other drugs of abuse.[13][14][15]...
