Congenital Abnormalities Quiz

• There are three types of congenital abnormalities: congenital anomalies of the chromosomes, congenital anomalies of the organs, and congenital anomalies of their parts from the standard of physiologic normality.
• The time factor is very important in the development of congenital abnormalities.
• The three groups of congenital abnormalities are: gametogenesis, blastogenesis, and embryogenesis.
• The complete, symmetrical, and undisturbed congenital abnormalities of the blastopagus are the most dangerous and the most harmful. They are two-headed babies with the same sex. They occur only during the early stages of intrauterine development and only between the 19th day of gestation and the 3rd month of pregnancy.
• The incomplete congenital abnormalities are those that are symmetrical but have some abnormalities. They are divided into those that are only partially developed (asymmetrical), those that are developed but not completely developed (mixed), and those that are completely developed (parasymptomatic).
• The congenital abnormalities of the embryo are caused by damage to the fetus between the 19th gestational day and the 3rd month of pregnancy. They are simple abnormalities, multiple simple abnormalities, or a sequence of abnormalities.

Test your knowledge about congenital abnormalities including anomalies of chromosomes, organs, and physiological normality. Learn about the time factor in their development and the groups of abnormalities such as gametogenesis, blastogenesis, and embryogenesis.
