How is mesoderm created?


Open in App
Solution

The formation of mesoderm:

  1. Mesoderm refers to one of the three germ layers of an embryo that develops during gastrulation.
  2. It is found to be present between the ectoderm and endoderm in the early embryo.
  3. In the early developmental stage, the egg possesses a darker animal region and a yolky vegetal region.
  4. Future mesoderm cells develop from animal region cells at the boundary of these two regions as an equatorial band.
  5. These future mesoderm cells are found on the surface in the early blastula.
  6. During gastrulation, the cells will rearrange until the mesoderm (and endoderm) are on the inside of the embryo.
  7. The mesoderm cells migrate to the interior.
  8. The central nervous system, excretory system, digestive system, and reproductive system are formed from the mesoderm layer.
