Quizplus · Accepted Answer

The neural tube is the structure that gives rise to the brain and spinal cord. It forms during the process of neurulation, which occurs early in embryonic development. The primitive streak and notochord are involved in the formation of the mesoderm, which gives rise to muscle, bone, and other tissues. The pharyngeal arches are involved in the development of structures such as the jaws and ears, while somites give rise to muscles and vertebrae.
