Prenatal alcohol exposure can damage the fetus during the whole pregnancy, but depending on once the exposure wake up determines which body organ is affected. Pregnancy deserve to be subdivided into three trimesters, each around twelve main long. Vital events in fetal advancement occur throughout each of this trimesters.

The bulk of structural breakthrough takes place during the an initial trimester (the 1st twelve mainly of pregnancy). Throughout the an initial trimester the musculoskeletal system is formed, together with the internal organ equipment (for example, the endocrine system, respiratory tract, cradle tract, and the worried system). The phase in advancement when organs are formed is described as organogenesis. Prenatal alcohol exposure throughout the an initial trimester can cause damage to specific cell populations an important to organ formation. Few of the most common physical defects encompass facial abnormalities, little skull circumference, skeletal and also muscle problems, and problems with internal organs.

An unfortunate truth is that throughout the early stages that the first trimester many women perform not realize they are pregnant, and also if lock drink alcohol, they may unknowingly reason structural damage (skeletal and also organ) to their unborn child.

Alcohol exposure at throughout the an initial trimester is not limited to skeletal and organ damage. Damages to the mind occurs as well, resulting in cognitive and behavioral problems.

Alcohol-induced brain damage can happen at any time during pregnancy (and during breast-feeding together well!). Throughout all 3 trimesters (and beyond), the major cells that the brain, the neurons and glia, are created from stem cells (neurogenesis and gliogenesis, respectively). Then, neurons multiply, grow and also establish your branches and connections. The lengthy axons the neurons become surrounded by myelin, i beg your pardon insulates and protects the neurons and enables electrical info to be transmitted follow me the axon. When a pregnant mom drinks alcohol throughout periods the neurogenesis, the alcohol actually kills the neural stem cells, reducing neurogenesis. Thus, the fetus can still construct neuronal abnormalities causing behavioral and learning deficits, without any type of manifestation that the physical abnormalities explained above.

Figure 5.7 The stages of advancement of the mind and spinal cord end the 3 trimesters are shown. Alcohol affects mind development throughout all 3 trimesters.

There is a common misconception that the lack of face abnormalities method that the child’s exposure come alcohol to be minimal and also therefore the child has a milder form of FAS. Top top the contrary, drinking throughout the second and third trimesters have the right to produce youngsters with major cognitive and also behavioral troubles in the absence of face abnormalities.

Alcohol consumed throughout pregnancy (during all 3 trimesters), can cause a wide variety of impacts on the fetus, varying from brain damage come musculoskeletal damage and growth retardation. In situations of episodic binge drinking (once in a while), injury come the brain and various other organs might be more selective. Damages to certain organs (including the brain) will depend on whether the certain organ is undergoing a far-reaching step in advance or a expansion spurt in ~ the time as soon as alcohol consumption takes place.
