What does a four-week-old embryo look like?

Embryogenesis:

1. It is the process by which the foetus develops from the zygote.
2. A four-week embryo looks smaller than a poppy seed and measures around 0.04 inches long.
3. After one month of pregnancy, the heart begins to develop in the embryo and begins to beat.
4. The brain and spinal cord also start developing.
5. Further differentiation of the neural progenitor cells into neurons and glia occurs over the following two weeks along with the development of digits.
