This teratogen has an enormous effect on the growth of the fetus and on the mental development of the unborn child. �� genetic teratogens which include chromosomal abnormalities and disorders and defects of the single gene. They can cause Dawn Syndrome and heart diseases, growth and mental retardation.
Teratogens are substances that could harm a developing fetus by affecting growth and causing birth defects or death. The use of tobacco during pregnancy is dangerous because the smoke causes the blood vessels to constrict.

A very large and essential part of prenatal care is the avoidance of teratogens. As we proceed I will mention the affects teratogens have on prenatal development, why the alcohol consumption should be reduced completely, and I will define what a teratogen actually is.

One of which, is what you are concerned with. It is known that in developed countries, like our own, the teratogen that is... The process is divided into three time periods. Those three periods consist of the germinal period, the embryonic period, and the fetal period.
The fetus transitions through three distinct periods of prenatal development, germinal, embryonic, and fetal arriving at the end of the third trimester with organized systems that allows for regulated functioning. During the course of prenatal periods the introduction of teratogens has the potential to disrupt the natural course of progress, ...
Towards the end of the the embryonic period, the teeth and external genitalia are formed. All of these have the greatest sensitivity to teratogens, especially alcohol. Also, any sort of teratogen can do damage during the fetal period as well, which is the period in which the organs are finishing their...
Stress impacts the development and growth of the fetus during the prenatal process and after the birth of the child that might persist into adulthood and cause more complications. Stress is an individual’s physical and mental reaction to the environment demands or pressures.

About 4-5% of birth defects are caused by exposure to a teratogen during pregnancy. Teratogens can impact a baby’s development as little as 10-14 days after conception. •http://www.chw.org/medical-care/genetics-and-genomics-program/medical- genetics/teratogens/.
Threshold for congenital effects in the embryo or fetus is most between 10–20 rads.
Babies who are born with Fetal Alcohol Syndrome can suffer from learning and intellectual disabilities as well as delayed development. They tend to have poorer memory and trouble processing information. They can often have trouble with attention and poor judgment skills.
Because the embryo is made up of only a few cells, damage to one cell, the progenitor of many other cells, can cause the death of the embryo, and the blastocyst will fail to implant in the uterus . Embryos that survive, however, will exhibit few congenital abnormalities.

A teratogen is any agent that causes an abnormality following fetal exposure during pregnancy. Teratogens are usually discovered after an increased prevalence of a particular birth defect. For example, in the early 1960’s, a drug known as thalidomide was used to treat morning sickness. Exposure of the fetus during this early stage of development resulted in cases of phocomelia, a congenital malformation in which the hands and feet are attached to abbreviated arms and legs. Teratogens can also be found at home or the workplace. The effect is related to type of agent, dose and duration, and time of exposure. The first half of pregnancy is the most vulnerable.
