medulla oblongata
Organ component of neuraxis that has as its parts the medullary reticular formation, inferior olivary complex and cochlear nuclear complex, among other structures[FMA]. The medulla oblongata lies directly above the spinal cord and controls vital autonomic functions such as digestion, breathing and the control of heart rate[GO].

metepencephalon, medulla oblonzata
Classical anatomical studies subdivided the vertebrate rhombencephalon into pons and medulla oblongata. (...) The medulla oblongata appears therefore as a tagma, that is, a group of segmental units (pseudorhombomeres, in this case) sharing some morphological and molecular characteristics, and in some aspects different from the segmental units present in adjoining brain regions, pons and spinal cord.[well established][VHOG]
