Ppt Prenatal Development Powerpoint Presentation Free Download Id The document summarizes the three main stages of pre natal development: the germinal period, embryonic period, and fetal period. the germinal period occurs within the first two weeks after conception and involves cell division and implantation in the uterus. the embryonic period lasts from weeks 2 to 8, where the zygote becomes an embryo and. Prenatal development occurs in three main stages conception, germinal (first two weeks), and embryonic (third through eighth weeks) where major organs begin to develop. 2. the fetal stage from the ninth week to birth sees continued growth and development until birth, including bone formation and ability to move. 3.

Prenatal development refers to the growth process that occurs from conception to birth. during that time, the fetus endures nine months of development. throughout prenatal development, the fetus is highly vulnerable to both genetic and environmental influences. those influences determine the fetus' future health, growth, and well weing. The document discusses pre natal development from conception to birth. it is divided into three periods: the germinal period from conception to 2 weeks, the embryonic period from 2 8 weeks, and the fetal period from 2 months until birth. during these periods, cells differentiate and organs form. support systems like the placenta and umbilical cord also develop. the document outlines.
