During the first two months of pregnancy, the embryo undergoes rapid cell division and begins to develop major organs and structures, including the brain, spinal cord, heart, and limbs. By the end of the second month, the embryo is referred to as a fetus, and its basic body plan is established.

The uterine tube is called the fallopian tube and the lining is made up of tiny hairlike, fingers called fimbria. The fimbria move the developing embryo along the fallopian tube to the uterus where it will embed itself. Here it will grow and develop until it is ready to be born in about 9-10 months..
An embryo typically develops a brain, heart, eyes, and legs within the first two months of pregnancy. By the end of the second month, these organs and structures are usually present and continue to develop throughout the rest of the pregnancy.
After ontogeny there is maturity.
The heart begins to beat at the end of 3 weeks. Our 'reptilian brain' develops within the first two months, but our conscious thought does not develop until six months into the pregnancy.
In humans, the embryo becomes the fetus at the beginning of the 11th week in gestational age (the 9th week after fertilization). This stage starts when the major structures have formed.
