Teratogenesis

Teratogenesis Terato is a Greek word meaning monster or ugly creature. The defective process by which the developing fetus or fetus in the mother's womb is functionally and structurally altered and gives birth as a deformed, deformed and disabled baby is called teratogenesis. In a word, teratogenesis is a congenital disability of the animal embryo. Fetal congenital disabilities are thought to be caused primarily by two mechanisms. One is for an error in the genetic programming of the fetus. The other is the result of interactions of the embryo with various toxic chemicals in the environment during fetal development.

The chemicals that cause this prenatal process of teratogenesis are called teratogens. Known chemical teratogenes are thalidomide, mercury, alcohol, lead, polychlorinated biphenols, and tetrachlorodibenzodioxin, various pesticides used in agriculture. In medical science, the study of the causes, processes, and signs of abnormalities in the physiological development of an organism due to teratogenesis is called teratology. In addition to congenital malformations, there may be other congenital malformations, such as mental retardation, delayed cognitive development, or any structural defect. The extent to which the embryo or fetus is affected depends on how the teratogens exaggerated them during development. The exact cause of the congenital disability is not yet clear. Chemicals that may harm the fetus should not be used - these include pesticides, fungicides, rodenticides, or cleaning products. Smoking, drugs, or alcohol should not be consumed during pregnancy - these teratogens significantly increase the risk of congenital fetal disabilities and other life-threatening conditions. [Md.
