Embryogenesis and the Developmental Consequences of Fetal Alcohol Exposure

Human embryonic development is the process by which a fertilized egg transforms into a fully formed embryo. This complex journey includes a series of carefully organized stages: fertilization, cleavage, blastulation, gastrulation, and neurulation. These stages take place during the first eight weeks of pregnancy and lay the foundation for the body’s organs, tissues, and systems. However, during this critical time, the embryo is highly sensitive to environmental influences. One of the most harmful substances during this period is alcohol. Fetal Alcohol Spectrum Disorders, or FASDs, are a group of lifelong conditions that result from alcohol exposure during pregnancy. This paper explores the stages of embryonic development and examines how alcohol affects this process, with a focus on public health concerns in the Rio Grande Valley.
