(...) 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] metepencephalon XAO:0003100 http://braininfo.rprc.washington.edu/centraldirectory.aspx?ID=698 EHDAA2:0001088 medulla oblonzata MAT:0000367 EMAPA:17550 MESH:D008526 The posterior region of the brain that is continuous with the spinal cord.
