The prenatal period is the time of development and growth of a child before his/her birth during this cycle the child is fully dependant on his/her mother for its nutritional necessities. Prenatal development essay prenatal development is the period in development from conception to the onset of labor perinatal period is the period beginning about the seventh month of pregnancy and continuing until about four weeks after birth. During each prenatal stage, environmental factors affect the development of the fetus the developing fetus is completely dependent on the mother for life, and it is important that the mother receives prenatal care, which is medical care during pregnancy that monitors the health of both the mother and the fetus. Prenatal influences on obesity the warm, nutrient- and hormone-rich environment of the uterus has a profound effect on fetal development brief or fluctuating changes in the intrauterine environment at critical or sensitive periods of the developmental process, as well as longer term alterations, could have irreversible, lifelong consequences. Teratogens----agents and conditions, including viruses, drugs, chemicals, stressors, and malnutrition, which can impair prenatal development and lead to birth defects or even death behavioral teratogens ---teratogens that tend to harm the prenatal brain, affecting the future child's intellectual and emotional functioning.
During the prenatal period there are many biological factors that can affect the child's development there are many environmental factors that can damage the fetus and interfere with a healthy development in the early years, development focuses on fast and constant changes involving physical. Having a healthy pregnancy is one of the best ways to promote a healthy birth getting early and regular prenatal care improves the chances of a healthy pregnancy this care can begin even before pregnancy with a preconception care visit to a health care provider. However, in some cases, genetic problems can emerge that may impact both current and future development down syndrome: also known as trisomy 21, down syndrome is the most common genetic anomaly during prenatal development. Prenatal development: environmental influences (cont) • maternal factors -nutrition and maternal weight • need 300 -500 more calories a day • need extra protein.
Prenatal development is influenced by various external factors the prenatal sensitivity of an individual to external factors, including xenobiotics, varies according to the stage of development. Prenatal growth has three distinct stages: the fertilized ovum (egg), or zygote (first 2 weeks) the embryo (from 2 to 8 weeks) and the foetus (from 2 to 10 lunar months) the human ovum at conception is about 01 mm in diameter. The negative impact on the fetus can include (ref6) poor growth, weak muscle tone, slow development of speech, or heart or facial malformation (ref4) factors in cigarette smoke can also pass into fetal blood, causing potentially serious problems.
Other factors - many other factors can affect fetal development, including heart disease, the mother's age (before 15 years and after 35 years is riskier), asthma, excessive stress or depression, diseases, and bleeding consult your physician if you are affected by any of these conditions. Prenatal development can be impacted by factors such as rh factor incompatibility, high blood pressure, diabetes, rubella and some sexually transmitted diseases.
During the prenatal period, there are many biological factors that can affect a child's development research conducted at rutgers university demonstrated how prenatal factors affect linguistic development and how postnatal factors are key components contributing to a child's cognitive development. Prenatal risk factors include chronic maternal illness, certain maternal infections, toxin exposures and nutritional deficiencies risk factors in the perinatal period include pregnancy-related complications, prematurity and low birth weight, and infection exposure during pregnancy or at time of birth. Protein seems to be the most critical element for development of neurological function, and prenatal protein deficiency can impact brain development at critical junctures 2 both nutrition and environment affect the ability and performance of the central nervous system.
The factors that place a pregnancy at risk can be a pregnant woman after the 20th week of pregnancy it can affect the mother's kidneys, liver, and brain. Today, it is well documented that there are many factors that could potentially harm or negatively influence the development of an unborn child during the prenatal period (1) these risk factors include a mother's age and her nutrition during pregnancy if there was drug, alcohol, or cigarette use. The prenatal period is the only time in development when interaction between mother and offspring cannot be directly observed and evaluated as discussed earlier in this volume, the scientific focus of fetal neurobehavioral. Indeed, the prenatal environment exerts profound influences on the development of an organism, and stressful events during pregnancy can induce alterations in the fetal environment resulting in early and long-term structural and functional consequences (maccari et al, 2003 wadhwa et al, 2001 weinstock, 1997.
Prenatal development factors that influence prenatal development ‐ negatively affect development if mom is an adolescent or over the age of 35. Genetic factors are traits passed through genes a baby inherits these genes fromtheir parents at the time of conception the parents genes combined create a blueprint for the zygot (single cell formed at conception) growth and development during the prenatal period these traits will be put in. Factors and hazards of infant development there are many factors and hazards that can influence an infant's development even before birth pregnancy is a very important event in a woman's life pregnancy is a very important event in a woman's life. What factors influence prenatal development life span development i chapter 9 2 ‐ negatively affect development if mom is an adolescent or over the age of 35.
