Correct Answer is C

Explanation

A. The neural tube and yolk sac have formed: By 8 weeks, the neural tube and yolk sac have formed, but this is not the criterion for defining a fetus.

B. The amniotic cavity has formed: The formation of the amniotic cavity occurs earlier in development and is not the defining feature of a fetus.

C. All of the organ systems are present: By the end of 8 weeks, the basic structures of all major organ systems are present, which is why the embryo is referred to as a fetus from this point onwards.

D. The mesoderm has formed: The formation of the mesoderm occurs earlier and is not the defining factor for fetal status. By 8 weeks, more significant development, including the presence of organ systems, has occurred.

A. Select one: B. the embryo; part of the placenta C. part of the placenta; the embryo D. part of the placenta; the yolk sac E. the embryo; the yolk sac

Correct Answer is B

Explanation

A. the embryo; part of the placenta. The embryoblast (inner cell mass) will become the embryo, but the trophoblast will become part of the placenta, not the embryo.

B. part of the placenta; the embryo. The trophoblast forms part of the placenta and helps in its development, while the embryoblast (inner cell mass) will develop into the embryo.

C. part of the placenta; the yolk sac. While the trophoblast does contribute to the formation of the placenta, the embryoblast (inner cell mass) develops into the embryo, not the yolk sac. The yolk sac is derived from extraembryonic mesoderm and endoderm, not the inner cell mass directly.

D. the embryo; the yolk sac. The embryoblast (inner cell mass) develops into the embryo, but the trophoblast does not become the yolk sac. The yolk sac is formed from structures surrounding the embryo, not from the trophoblast itself.
