The extra-embryonic membrane in humans that prevents desiccation of the embryo inside the uterus is the amnion.
Explanation:
- The amnion is an extra-embryonic membrane that surrounds the developing embryo in the uterus.
- It is filled with amniotic fluid, which provides a protective cushion for the developing embryo and prevents desiccation (drying out).
- The amniotic fluid also helps to regulate the temperature of the embryo and provides a medium for fetal movement.
- The amnion is formed from the inner cell mass of the blastocyst and begins to form around the embryo at about 8 days after fertilization.
- As the embryo grows, the amnion expands and the volume of amniotic fluid increases.
- The amnion eventually fuses with the chorion (another extra-embryonic membrane) to form the amniochorionic membrane, which forms the outer layer of the placenta.
In summary, the amnion is the extra-embryonic membrane in humans that prevents desiccation of the embryo inside the uterus by surrounding it with amniotic fluid.
