The nervous system and brain are derived from the ectoderm, which is one of the three primary germ layers that form during embryonic development. The ectoderm gives rise to various structures, including the skin, hair, nails, nervous system, and sensory receptors. Muscles and bones are derived from the mesoderm, while the digestive and respiratory systems are derived from the endoderm. The circulatory system is derived from both the mesoderm and the endoderm.
