Quizplus · Accepted Answer

The three primary divisions of the developing neural tube are the hindbrain, midbrain, and forebrain. These structures will give rise to the brain and spinal cord. The hindbrain will give rise to the medulla, pons, and cerebellum. The midbrain will give rise to the tectum and tegmentum. The forebrain will give rise to the diencephalon and telencephalon. Therefore, choice B is the correct answer as it includes all three of these primary divisions.
