Embryonic Period. the embryonic period is weeks 3-8 of development; the three germ layers- ectoderm, mesoderm, and endoderm- form the tissues and main organ systems and the body becomes recognizably human.
The pre-embryonic period is the first 2 weeks of development (the first 2 weeks after fertilization), when the single cell produced by fertilization (the zygote) becomes a spherical, multicellular structure (a blastocyst). This period ends when the blastocyst implants in the lining of the uterus.
