Ectoderm cells are the precursors of the entire nervous system, including both the brain and the spinal cord. Glial cells and neurons are both derived from ectoderm cells. Mesoderm cells contribute to the development of the skeletal system, muscles, and other organs, but not to the nervous system. Endoderm cells give rise to the lining of the digestive and respiratory systems, but not to the nervous system.
