The external germinal layer cells to form the developing nervous system, sensory system and skin. The mesoderm (embryonic layer media) develops the heart, vascular system and connective tissue (CT). Endoderm layer (innermost embryonic tissue) develop internal organs as the intestines, lungs and reproductive system. In the middle of the inside of the embryo, there is a slight thickening, a neuronal line that later will develop your child’s nervous system.
