What are teratogens? Provide an example of a common teratogen and the overall affects of exposure
Teratogens are a broad group of environmental agents such as chemicals, drugs, infections, and/or radiation that negatively affect the normal course of cell growth and development in an unborn child. Fetal alcohol syndrome (FAS) or fetal alcohol effect (FAE) are the results of exposure to one of the most familiar teratogens, alcohol during pregnancy. FAS results in a small head circumference, unusual facial characteristics, and other physical deformities. Many infants are developmentally delayed. FAE is characterized by learning and behavior problems that are unfortunately not apparent until later in life.
