(...) 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] DMBA:17352 EFO:0000924 EHDAA2:0001088 EHDAA:7588 EMAPA:17550 EV:0100275 FMA:62004 GAID:590 MA:0000206 MAT:0000111 MAT:0000367 MBA:354 MESH:D008526 MIAA:0000111 OpenCyc:Mx4rvVjxSJwpEbGdrcN5Y29ycA OpenCyc:Mx4rwCqnXJwpEbGdrcN5Y29ycA 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]. Posterior portion of the hindbrain which controls respiration, heartbeat, digestion, and swallowing as well as some locomotor responses.[AAO] TAO:0000545 The posterior region of the brain that is continuous with the spinal cord.
