Environmental Effects On Prenatal Development

Birth, of course, does not mark the beginning of human development; rather, development begins at conception. Once the fertilized egg is produced, there are many events and hazards that can influence how it develops and becomes a person. During the nine months of prenatal development is critical in determining the health and optimal structure of a newborn. (Lazinski, 2008). Can be tested through ultrasound sonography, fetal MRI, chorionic villus sampling, amniocentesis and blood screening. While harmful substances that affect the development of the fetus include caffeine, alcohol, nicotine, drugs, X-ray radiation, diseases, and emotional state of the mother. This research compares the effects of these hazards on prenatal development as related to the textbook.

(Nelson, 2012) After the conception of the egg the first three months are vital to prenatal development, as organogenesis and development of the organs take place, the environmental influences are highly sensitive. Teratogens can do more damage during the formation of the fetus during this time and cause a threat from developing fully. Prenatal testings is useful in making sure whether the fetus is developing normally, as the baby is entirely dependent on the mother’s health for survival. Baby 's sex can be determined in as little as seven weeks into pregnancy and is able to smile, frown, suck and swallow in just the first trimester (first 3 months) of
