The endoderm layer gives rise to the digestive system, lungs, liver, pancreas, and other internal organs. The ectoderm layer gives rise to the skin, hair, nails, and nervous system, while the mesoderm layer develops into the muscles, bones, cardiovascular system, and kidneys. "Zygoderm" is not a valid embryonic layer.
