The Period Of Foetus – Two months to birth

The period of foetus is the third stage of prenatal development. It extends from the end of the second month to the time of birth, which normally occurs at the end of around 280 days. It is characterized chiefly by growth and development, as all the body parts and structures have already been established in the period of embryo. At the end of the third month, the foetus measures around ten inches and weight about 250 gram. By the end of the eighth lunar month it measures about 16 inches and weighs about 2 kg. At full term, that is, 280 days, the foetus measures about 19 inches and weighs 3 to 3.5 kg. However, there are large individual differences in these estimates. The estimate may vary on various accounts say for example, the mother is weak or mother takes less nutrition than she is supposed to, or her emotional status.
