Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation. The normal period of gestation is about 40 weeks. The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days. The stages of human development include, in order: zygote, blastocyst, embryo, and fetus A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula. Changes to the form of the embryo come from differentiation and growth.
