The midbrain corresponds to the mesencephalon in embryology. The brain develops from three primary vesicles: forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon). From the forebrain, the telencephalon and diencephalon arise; from the hindbrain, the metencephalon and myelencephalon arise. The midbrain stays as a single region—the mesencephalon—so that is the division that matches the midbrain. The other terms come from different primary vesicles: diencephalon and telencephalon are forebrain derivatives, while rhombencephalon is the hindbrain.
