Prenatal Period
• From conception to birth, the rate of growth and development is very rapid – 40 weeks (9 months)
• If the pace continued after birth= 6’0” & 200 lbs. @ 1 year!
• Three Stages in Prenatal Period:
1. Germinal Stage • First two weeks after conception • “Zygote” is created through
fertilization of egg• Zygote implants itself in uterine
wall to begin growth process
2. Embryonic Stage • Two weeks through 2nd month • Now called an “Embryo”• Cell division is specialized• Most major birth defects happen
in this stage
3. Fetal Stage • Two months through birth • Now called a “fetus”• Becomes capable of movement• At six months can usually
survive premature birth.
