Document Summary

Conception: 1 egg and 1 sperm join together to form 1 single cell (& the cell divides over and over again, zygote: a fertilized egg with 100 cells that become increasingly diverse; at about. 14 days the zygote turns into an embryo: at 9 weeks, an embryo turns into a fetus; teratogens and chemicals or viruses that can enter the placenta and harm the developing fetus. At birth, most brain cells are present. After birth, the neural networks multiply resulting in increased physical and mental abilities. Newborns are born with different re exes and different types of cries. The development of the brain unfolds based on genetic instructions, causing various bodily mental functions to occur in sequence called maturation. Physical development : sitting - 6 months, crawling - 8-9 months, beginning to walk - 12 months, walking independently - 15 months.
