What is the most superior portion of the midbrain?
The most superior part of the brainstem is the midbrain which continues behind the pons and down to the medulla. The more anterior, superior part of the brainstem is the pons and the more posterior, inferior part of the brainstem is the medulla, although there is some overlap.
Is the medulla oblongata superior or inferior to the rest of the brain?

Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
What is in the medulla oblongata?
