22+ Brain Diagram Medulla Oblongata Background. The medulla oblongata is located in the brain stem, anterior to (in front of) the cerebellum. It's one of three main regions of the brainstem, the other two being the pons and midbrain, in ascending order.
The image on the left is a side view of the outside of the brain, showing the major lobes (frontal, parietal, temporal and occipital) and the brain stem structures (pons, medulla oblongata, and cerebellum).

The medulla oblongata is a roughly cylindrical mass of nervous tissue that connects to the spinal cord on its inferior border and to the pons on its superior border.
The medulla contains mostly white matter that carries nerve signals ascending into the brain and descending into the spinal cord. The midbrain, pons and medulla oblongata are often together termed as the brain stem (sometimes only the pons and medulla oblongata are referred to as the brain stem). The mesencephalon forms the midbrain, the metencephalon forms the pons and cerebellum, and the myelencephalon forms the medulla oblongata (fig 1). These two hemispheres make up the cerebral cortex.
