Quizplus · Accepted Answer

The embryonic stage is the stage of prenatal development that occurs from the second to the eighth week after fertilization. This stage is particularly vulnerable to teratogens, which are substances that can disrupt normal development and cause birth defects. Miscarriages are also most likely to occur during this stage, as major organ systems are developing rapidly and any abnormalities or disruptions can lead to loss of the embryo. The zygotic stage occurs immediately after fertilization and lasts for only a few days, while the germinal stage lasts until implantation (around 2 weeks after fertilization) and does not involve as much development as the embryonic stage. The foetal stage (from 9 weeks until birth) is a time of further growth and maturation rather than major development, and miscarriages are less likely to occur during this stage.
