Question

Quizplus · Accepted Answer

Prenatal development proceeds unevenly, meaning that different parts of the body and different systems develop at different rates. For example, the human brain development begins at the third week of gestation and continues after birth, whereas the formation of the fingers and toes is complete by the eighth week. The timing of development is fundamentally important in prenatal development, as different developmental stages and windows have different critical periods during which basic body structures are laid down and organs develop. Environmental factors such as maternal nutrition, exposure to toxins, and stress can also influence prenatal development. Sequencing, or the order in which different developmental events occur, is also crucial for proper prenatal development.
