First, an adverse prenatal environment can have detrimental effects on later behavioral and health outcomes. Diseases and conditions such as heart disease, diabetes, obesity, etc., can also be passed through genes, thereby affecting the growth and development of the child adversely. Physical Environment. . In utero, nicotine targets the fetal . Sensory input promotes and shapes cognitive development. While some of these factors are within the parents' control, biological factors are less controllable. Radiation increases the risk of childhood cancer, as well as emotional and behavioral disorders; because of this, it is recommended that pregnant women avoid x-rays unless .

Factors influencing prenatal risks: There are several considerations in determining the type and amount of damage that might result from exposure to a particular teratogen (Berger, 2005). Extreme heat events can lead to dehydration and kidney failure in pregnancy, which by extension, can affect the baby's growth and development," Dr. Milbank says. The emotional environment The nature of the child's interpersonal relationships. This is based on a large literature showing that prenatal environmental factors (e.g., maternal nutrition, immune response, smoking/drug use, teratogens, etc.) Harmful environmental elements that can affect the fetus are known as teratogens. Pre-Pregnancy and prenatal care can help prevent complications and inform women about important steps they can take to protect their infant and ensure a healthy pregnancy. neurobehavioral development. The first chapter of the report addresses what the research suggests about the short- and long-term effects of prenatal exposure to alcohol and other drugs. Teratogens are environmental factors that can cause a birth defect. Gender. For example, by late in pregnancy, fetuses can distinguish different sounds, including music and their mother's voice. Environmental influences on fetal and neonatal development can affect neural, reproductive, immune and cardiovascular function in adult humans and animals. The Prenatal Environment of the Developing Organism 1 The developing unborn baby is being studied today in ways that were not possible a short time ago . The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include A teratogen is any substance or agent in the environment that can have a detrimental effect on a developing fetus. Chapter 3: Heredity, Prenatal Development, and Birth. Photos Courtesy of Will Hastings (Left), Mamma Loves (Center) and MIKI Yoshihito (Right) Objectives: At the end of this chapter, you will be able to. Prenatal development is an important period related to development compared to other periods. Several risk factors may affect fetal growth and development during pregnancy. Aberrant fetal growth is associated with morbidities and mortality during childhood and adult life. The main concern of a society is to ensure healthy growth and development. Prenatal exposure to a dangerous substance is only harmful in the first trimester of . The negative impact on the fetus can include (ref6) poor growth, weak muscle tone, slow development of speech, or heart or facial malformation.

Moreover, hurricanes and floods can damage homes and communities, increasing exposure to toxins and mold and diarrheal illness from contaminated water and food supply. Posted June 12, 2021 . Stimulation, in adequate quantity and intensity, promotes establishment of, and "shapes," neural pathways in the brain. Furthermore, we aimed to report their . However, environmental factors and nurturing can bring the best out of the already present qualities in the genes. The egg and the sperm each contain 23 chromosomes, which make up our genes. The fetus depends on the mother for life and becomes vulnerable to different environmental influences that can affect their development. The environment can have an important influence on development, and this also includes the prenatal period. After all, it is natural for parents to have their child's best interests at heart. 4 A number of teratogens can harm the fetus, including: Maternal Drug Use: The use of substances by the mother can have devastating consequences to the fetus. What are 3 environmental factors that affect prenatal development? Check Writing Quality. Factors affecting pre-natal development. Define gene, chromosome, and gamete. In humans, genetic variation begins with an egg, several million sperm, and fertilization. They can affect children throughout their development, particularly during critical times such as the prenatal period and early childhood. The second chapter discusses environmental factors which, by themselves or in combination with the effects of prenatal exposure to alcohol or other drugs, can affects a child's development. Although genetic and environmental factors are known to influence in utero growth, their . Prenatal environment is the mother's body. The pathogenesis of adverse pregnancy and birth outcomes is multifactorial, involving complex interactions between environmental influences, genetics, and epigenetic mechanisms. It interferes with the fetal development, specifically affecting the nervous system. Rubella is the most widespread of the viruses that . In the early times, many scientists believed that the placenta was a barrier that protected the growing . Developmental defects in animals may result in early embryonic death, foetal death, mummification, abortion and stillbirths. These include: However, the In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack. Second, the size of the effect of the prenatal environment is, in many cases, reduced when familial factors are taken into account. The organism gets nutrients through the mother's placenta. The growth that happens during the nine months of prenatal development is nothing short of astonishing, but this period is also a time of potential vulnerability. 2 Environmental Factors t hat Might Affect t he Infant's Development Infant development begins from conception, through birth to adulthood. Research conducted at Rutgers University demonstrated that prenatal factors affect linguistic development and postnatal factors contribute to a child's cognitive development.
