Concept in Definition ABC

Embryology is the science that deals with the study, the training and the development of embryos.

The study of this begins from when the fertilization of the ovum by the sperm occurs, giving rise to the formation of the egg or zygote, until the moment of the birth of the living being. Once all the major structures and organs have been generated, the embryo It will be called a fetus.

Among the main contributions made by embryology are: filling the gap that exists between prenatal development and obstetrics, provide important knowledge about the beginning of human life and the different modifications that occur while the prenatal development, provides answers to understand the causes of why certain variations in the human structure, explains relationships abnormal and normal.

Three branches are distinguished within embryology: comparative embryology (compares the embryos of living beings), embryology chemistry(offers concrete chemical bases regarding orthogenic development) and

modern embryology (Developed recently, at the beginning of the 21st century, it is related to sciences such as genetics, the medicine and biochemistry).

It should be noted that embryology is closely linked to disciplines such asanatomy and histology and very especially to the teratology what is that discipline which focuses on the study of congenital malformations of the embryo, mostly, the latter linked to factors genetic on the one hand and on the other hand with environmental causes that alter the normal development of the embryo.
