What can cause developmental abnormalities in the developing embryo and fetus?
Congenital (“present at birth”) abnormalities and the loss of embryos and fetuses prior to birth are caused both intrinsically and extrinsically. Those abnormalities caused by genetic events (mutations, aneuploidies, translocations) are called malformations.Click to see full answer.

Congenital (“present at birth”) abnormalities and the loss of embryos and fetuses prior to birth are caused both intrinsically and extrinsically. Those abnormalities caused by genetic events (mutations, aneuploidies, translocations) are called malformations.Click to see full answer. In respect to this, what can cause abnormalities to occur during embryonic development?There are many different ways that developmental abnormalities can occur the 3 major types are Genetic (inherited), Environmental (maternal) and Idiopathic (unknown, not determined) derived abnormalities. The environmental factors that cause or lead to any of these abnormalities are described as teratogens.Similarly, what is the correct health hazard that causes disruption to an embryo or fetus? A teratogen is an agent that can disturb the development of the embryo or fetus, resulting in spontaneous abortion, congenital malformations, intrauterine growth retardation, mental retardation, carcinogenesis, or mutagenesis. Known teratogens include radiation, maternal infections, chemicals, and drugs. Beside above, how do teratogens affect the developing fetus? Teratogens are substances that may produce physical or functional defects in the human embryo or fetus after the pregnant woman is exposed to the substance. Additionally, teratogens may also affect pregnancies and cause complications such as preterm labors, spontaneous abortions, or miscarriages.What stage of fetal development is associated with the greatest risk?Harmful exposures during the first trimester have the greatest risk of causing major birth defects. This is because many important developmental changes take place during this time. The major structures of the body form in the first trimester.
