Factors that Negatively Effect Fetal Development Pregnant women that smoke cigarettes on a daily basis can greatly harm their fetus. The Tobacco smoke in cigarettes greatly reduces fetal growth through the presence of nicotine, carbon monoxide, hydrogen cyanide, cadmium and various other aromatic hydrocarbons, but the two most dangerous chemicals that are found in cigarettes are nicotine and carbon monoxide. Nicotine causes the babies heart rate to speed up, reduces placental vascularisation
Lead Toxicity: Its Effects on Fetal and Infant Development Lead toxicity has been an area of unending research in recent years. There have been positive and negative correlation’s relating its toxic effects to both child developmental deficiencies and adult regression problems. This review will focus on the problems associated with the children. It will discuss various routes of entry of lead into the child’s system, both prenatally and postnatally, the mechanisms employed by lead to cause the
Organogenesis, Myogensis, neurogenesis and opsgenesis; these four things are key components to the construction of fetal development, which includes the embryo, zygote and fetus. In this paper I will examine, discuss and describe the changes in fetal development such as weight, length, growth of limbs and how everything correlates with the mother also. The zygote is the result of a female egg being fertilized by a sperm cell. For two consecutive weeks rapid cell division in effect, but it only takes
The Effects of Smoking on the Developing Fetus The exposure of the fetus to nicotine during development has several effects. The most well known result of smoking is low birth weight of the infant. There are also some studies that reveal nicotine as a drug that can affect the brain of the developing fetus. Nicotine also has direct effects on the neurotransmitter systems in the CNS and may cause a decrease in cell growth which could result in mental impairment. The correlation between maternal
Vitamin A is a fat-soluble nutrient. It plays an important role in vision, maintenance of epithelial cells, immune functions, and participates in the processes of growth, development and reproduction. Vitamin A is characterized into two chemically distinct yet structurally related forms. The first form is retinoid, which is present only in foods of animal origin, such as fish and organ meats. “Retinoid is also known as 'preformed vitamin A' because it can be metabolized directly into compounds that
Violence in America Violence in America’s society is definitely a major problem. This problem can be traced back as far as fetal development. It seems that in most cases of bad treatment, the families come from poverty or bad neighborhood areas. The whole main purpose of this speaker was to develop a good understanding on why most of the violent crimes occur in today’s hurting society. It is not rocket science to realize that most angry violent acts are due to a disturbed child or individual that
Against Abortion Why is it that by 21 days into the fetal development the baby's heart begins to beat, but yet in most people's eyes the baby is still not 'technically' alive' That heart beat means nothing, it doesn't represent a human person whom God has created in his own image and has had a plan for that baby ever since the beginning of time. To most people that statement isn?t allowing women and their families freedom of choice. And yet that baby isn't given any say in its freedom to live
at any stage of its development if abortion is performed. Discussions between both sides are usually very competitive, and sometimes violent, so any attempt at coming to a mutual agreement is drowned out. How can anyone hear if they refuse to acknowledge the other side, except to argue? Since the Roe v. Wade decision legalized abortion, compromises that limit or allow abortion have taken two forms: those based on the reasons for abortion, and those based on fetal development at different stages of
cause of dwarfism was a breakthrough because dwarfs in the past were simply regarded as inexplicable freaks.But now there is biological evidence of a gene, in which,“the mutation, affecting growth, especially in the long bones, occurs early in fetal development” (Kennedy 4).It is from this sort of mutation that two parents of average size can give birth to a dwarf.Trudi’s parents in Stones from the River were of normal height, so her dwarfism ... ... middle of paper ... ...d not have to suffer the
the brain. It begins to be noticed in a person's late teens through twenties. Signs of it can be seen from early childhood and it is now being hypothesized that it is actually present during adolescence (1). Since this hypothesis extends to fetal development, brain formation in the earliest stages is effected. The alteration of pathways and deviation of neurotransmitters from normal arrangement is believed to be a factor behind the affliction. The brain of these individuals forms differently. Neurotransmitters
hand-flapping motions commonly associated with autism, as well as inability to relate to the outside world, limited social skills, lack of concentration, and hypersensitivity to certain stimuli-particularly noise (1). Perceived causes include poor fetal development, genetics, allergies, and a lack of crucial enzymes. Because for many years the disorder was thought to be a result of poor parenting, only recent studies have begun any attempts to identify the causes of childhood autism. Many diagnosis and
1. Describe the normal events of fetal development. How does malnutrition impair fetal development? Fetal development begins with the fertilization of an ovum; the female reproductive cell, capable of developing into a new organism upon fertilization, by a sperm; the male reproductive cell capable of fertilizing an ovum. Three stages follow fertilization: the zygote, the embryo, and the fetus (Whitney & Rolfes, 2016, p. 475). The initial product of the union of ovum and sperm; a fertilized ovum,
factors that affect development. Some of those are factor, which have a direct bearing on prenatal life, later on manifest postnatal. The human body is a highly organized system with trillion of cells communicating with each other to ensure proper functioning. However those functions, can be enhance or impaired by endogenous or exogenous agent, which act in concert to produce effects during prenatal life. These effects might have consequences on emotional and cognitive development of a child postnatal
Effects of Alcohol and Fetal Alcohol Syndrome Works Cited Missing Alcohol plays a major role in society today. It is constantly being in our minds through advertisements, whether its commercials or billboards, holidays, or even just at the popular social scene. Alcohol is consumed for many purposes, such as celebrations, to increase romance, out of boredom, or a way to relax. Alcohol is a drug that is depended upon by the majority of our society. Nonetheless, alcohol has very damaging effects
Use of Human Fetal Tissue in Research is Morally Repugnant Research on human fetal life involves numerous complex medical, moral, and legal aspects. It is not always easy, nor desirable, to seal off one aspect from another. Both sides of fetal tissue use will be equally focused on as a moral issue. The topic is a timely and important one because research on human fetal life is reportedly a growing industry and the subject of legal developments both in the United States and around the world
one at best. The question facing many scientists and policymakers involved in embryonic stem cell research is, which is more valuable – the life of a human suffering from a potentially fatal illness or injury, or the life of human at one week of development? While many argue that embryonic stem cell research holds the potential of developing cures for a number of illnesses that affect many individuals, such research is performed at the cost of destroying a life and should therefore not be pursued.
Related to Fetal Tissue Research The use of fetal tissue in biomedical research has been a hot topic for debate in social and political forums ever sense the landmark decision in the 1973 case of Roe vs. Wade (Beller & Weir 182). The decision of the Supreme Court to give women the right to abort a fetus without having a medical reason for doing so, sparked controversy which has affected any medical procedure or research dealing with fetuses (Bellar &Weir 182). Supporters of fetal tissue research
not only more fetal murders but also more mothers will die. None of the methods women use to abort are completly safe. One of the most common methods used is Suction Aspiration. The doctor uses a special tool to suck the baby into a collection bottle. Great care must be taken to prevent the uterus from being damaged, which would cause hemorrhage. A woman with hemorrhage will need a blood transfusion that could cause her AIDS. Also infection may easily occur if fetal tissue is left behind
the block, the place where they "burn bodies of people" is pointed out. It turns out that it was an incinerator for hazardous waste products transported from New York City hospitals. Nope, no bodies just things like the occasional amputated limb, fetal tissue, needles, soiled bedding, and used bandages are piled up until they can be burned. On days that they burn the air is heavy and... ... middle of paper ... ...he problems. The problems do not root from one individual nor do they stop at another
Dogfish Shark Dissection Lab Preparation for Lab & Learning the Anatomy Before any actions may ensue, the correct tools must be collected. It is important to have the following: scalpel, dissection scissors, tweezers, latex gloves, forceps, teaser needles (angled and straight), and a tub large enough to hold the full length of the shark. In order to start the examination and observation, the first step before dissection, the bag containing the dogfish specimen must first be cut open and drained of
