The brain stem is the bottom-most portion of the brain, connecting the cerebrum with the spinal cord. The midbrain, pons, medulla oblongata, and reticular formation are all part of the brain stem. The midbrain is the short portion of the brain stem between the pons and the cerebral hemispheres. The top of the midbrain is called the tectum (or tectal area). The third and fourth cranial nerves originate in the midbrain.
What are the parts of the brain? The main parts of the brain are the frontal lobe, temporal lobe,  occipital lobe, parietal lobe, hypothalamus, cerebrum, brain stem  ,and cerebellum. In addition, the brain â¦contains the corpus  callosum, pituitary gland, hypothalamus, and thalamus. The medulla  oblongata and pons are parts of the brain stem.
