Prenatal period conception: sperm fertilizes egg > zygote. 1. germinal stage: 0-2 weeks, zygote - ovulation to implantation egg leaves ovary, travels to opening of fallopian tube, fertilized and becomes zygote, reaches uterus in a week, implants itself in wall of uterus, triggers formation of nutrient-rich placenta. Rst 36 hours: cell divides and multiplies, zygote moves through fallopian tube to uterus4th day: zygote > blastocyst. 3. fetal stage: 9-40 weeks, fetus development of muscular and skeletal system, brain begin to hiccup, see, hear, sleep.
