Quizplus · Accepted Answer

Teratogens can affect the central nervous system throughout the prenatal period, which includes the embryonic and fetal periods. The nervous system begins to develop during the embryonic period, and continues to develop and mature throughout the fetal period. Therefore, exposure to teratogens during both of these periods could result in various neurological defects and disorders. Teratogens can also affect other aspects of fetal development, such as the cardiovascular and respiratory systems.
