The Greek civilization came after the Minoan. About 2000 B.C., people from the north moved southward into the peninsula of Greece. These people-the Achaeans built walled cities in the southern part of Greece. Their most important city was Mycenae.
In human development, a fetus (/ËfiËtÉs/ ; plural fetuses), also spelled foetus, is a prenatal human between its embryonic state and its birth. The fetal stage of development tends to be taken as beginning at the gestational age of eleven weeks, i.e. nine weeks after fertilization.t the start of the fetal stage, the fetus is typically about 30 millimetres (1.2 in) in length from crown to rump, and weighs about 8 grams. The head makes up nearly half of the fetus' size. Breathing-like movement of the fetus is necessary for stimulation of lung development, rather than for obtaining oxygen.
All of the processes of embryo development are described by the term embryogenesis. The embryo is called a fetus after the completion of this stage of development. The stage of prenatal development that occurs from the end of the embryonic period until birth is called the fetal period.The most notable development during this stage is the dramatic change in size that takes place. This is the baby's final preparation for life outside the womb.hink of Steve and Jennifer's baby as spending the germinal period looking for a place to live.
