Fetuses can learn and remember while in the womb, and they respond to their mother’s voice?. Explain prenatal development from fertilization to birth. Understand different biological process’ in all phases of prenatal development. Define key vocabulary. Chart different phases in . somitogenesis. Formation of the Digestive Cavity. At the Blastula stage, the embryo forms a fluid filled ball of cells. During Gastrulation, the blastula caves in on one end to form a Gastrula.
