The process of
prenatal development occurs in three main stages and they are listed in order;
1. Germinal Stage - begins at conception when the
sperm and egg cell joined in one of the two fallopian tubes.
2. Embryonic Stage - begins at the beginning of
the third week after conception. This stage plays an important role in the
development of the brain.
3. Fetal Stage - begins during the ninth week
and lasts until birth.
