Medulla oblongata is the terminal part of the brainstem. It sits in the posterior cranial fossa, below the tentorium cerebelli . The rostral medulla is continuous with the pons superiorly, with which it forms the pontomedullary junction.

The most inferior portion of the midbrain is the medulla oblongata, which connects the pons to the spinal cord. It meets the spinal cord at the level of the foramen magnum. The anterior portion of the medulla oblongata contains the pyramids.
