Question

Quizplus · Accepted Answer

The midbrain, pons, and medulla oblongata are all located in the lower part of the brain, below the tentorium cerebelli which separates the cerebral hemispheres from the cerebellum. This region is known as the infratentorial region. Therefore, option D is the correct answer. A is incorrect because the medulla oblongata is a part of the brainstem, not the diencephalon. B is incorrect because the hypothalamus is a structure in the diencephalon, not the brainstem. C is incorrect because the executive functions are primarily associated with the prefrontal cortex, not the medulla oblongata.
