title: Neuronal group connecting the nucleus retroambiguus with nucleus ambiguus.
abstract: The nucleus retroambiguus is connected to the ambiguus rostrally to the crossing pyramidal fibers and laterally to the crossing lemnisces. The lateral reticular nucleus is positioned laterally and ventrally to the neurons of the connection. The neurons belonging to the connection are medium-sized. Their long dendrites are directed mainly medially, dorsally and ventrally. Medially directed dendrites ascend into the central nucleus of the medulla oblongata. Fibers of the lateral vestibulobulbospinal tract pass through the area of the connection. The tracts of the corticobulbar and medial reticular formations are found in the vicinity of the neuronal group described above. It is not impossible, however, that other, as yet unknown, tracts also pass in the neighbourhood.
