Introduction
The term used to describe the early three (3) layered embryo following gastrulation when it now has a structure consisting of the 3 germ cell layers: :ectoderm, mesoderm, endoderm. In humans, this developmental stage occurs during week 3.
Do not confuse the term "germ cell layers" with "germ cells", which refer to the egg and sperm.
