Embryonic Pole vs Fetal Pole

The embryonic pole refers to the early stage of development after fertilization and implantation of the embryo in the uterus. During this stage, the embryo undergoes rapid cell division and begins to develop the basic structures and organs. The embryonic pole is characterized by the presence of the gestational sac, yolk sac, and the early formation of the fetal tissue.

On the other hand, the fetal pole refers to a later stage of development when the embryo has grown and developed further. The fetal pole is typically visible during ultrasound examinations around 6 to 7 weeks of gestation. It appears as a thickened area at one end of the gestational sac and represents the early development of the fetus. Over time, the fetal pole continues to grow and develop into a recognizable human fetus.

In summary, the embryonic pole refers to the early stage of development after fertilization, while the fetal pole represents a later stage of development when the embryo has grown and developed further, and the fetus is starting to take shape.
