Prenatal development is when a baby is developing in the womb from conception to birth. Though Prenatal development refers to the processes involved in human embryogenesis, marking the transition between embryonic and fetal stages. The prenatal period begins with fertilization (conception) and ends with live birth. The zygote divides through mitosis to form a multicellular embryo, which implants in the uterus wall. Although the placenta connects the developing fetus to the uterine wall for allowing nutrient uptake, waste elimination, and gas exchange via the mother’s blood supply. The developing embryo undergoes various stages of cellular differentiation until birth.
In human-being pregnancy, prenatal development is also called antenatal development. The development of a human embryo starts with fertilization and continues as fetal development. The embryo is formed by the end of the tenth week. It has its basic form and is called a fetus. The next period is when the baby’s organs start to develop. This fetal period is described by the parts of the baby. The major events are also listed according to their gestational age.
In mammalian pregnancy, prenatal development is the development of a baby from the time the embryo implants in the uterus through birth. Prenatal development is the dynamic socialization of parents, usually by their children. It isn’t only limited to fathers either—many academic studies have addressed this issue with regard to mothers as well.
