em·bry·o·gen·e·sis

(em'brē-ō-jen'ĕ-sis),
That phase of prenatal development involved in establishment of the characteristic configuration of the embryonic body; in humans, embryogenesis is usually regarded as extending from the end of the second week, when the embryonic disk is formed, to the end of the eighth week, after which the conceptus is usually spoken of as a fetus.
[embryo- + G. genesis, origin]
