A large nuclear structure on the periphery of the reticular formation gives rise to the first portion of the facial nerve. This is the nucleus facialis (Nf). The fibers arising in it pass backward and inward to\\ard the lloor of the fourth ventricle in the form of a heavy spray. This nucleus in tarsius is nearer the periphery of the section than in any of the other primates and the fibers constituting the first portion of the facial nerve are coarser than observed in other Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Tilney, Frederick, 1875-1938; Riley, Henry Alsop, 1887-.
