Why do we study human embryology ?

Human embryology is a science studying the development of a human in the woomb of a pregnant woman. Many interesting progresses occur in the creation of a human in the woomb. Beginning with a three layer embryo -entoderm,mesoderm and ectoderm- an evolution takes place. The alteration of a neural plate to a neural groove and at last to a neural tube is a beginning of the creation of our central nervous system.
