The myelencephalon or medulla oblongata (bulb is an archaic term) is the rostral continuation of spinal cord. It is the caudal part of the brainstem.
It ends cranially at the medullopontine sulcus at the posterior border of the pons. Its caudal border lies along a plane above the root fibers of the first cervical segment.
