The Duct of the Submaxillary Gland (Wharton s) is about two inches inlength, and its walls are much thinner than those of the parotid duct. It opens bya narrow orifice on the summit of a small papilla at the side of the frsenum from thence, it is found to pass between the sublingual gland and the Genio- Fig. A Highly-magnified Section of the Submaxillary Gland of theDog, stained with carmine (Kolliker): a, cross-section of smallsalivary duct; b, an alveolus containing salivary cells; c, cres-cent of Gianuzzi. 854 ORGANS OF DIGESTION. hyo-glossus muscle, then backward and outward between the Mylohyoid and theHyo-glossus and Genio-hyo-glossus muscles, to the deep portion of the gland, whereit commences by numerous branches. On the Hyo-glossus muscle it lies betweenthe o-ustatory and hypoglossal nerves, but at the anterior border of the muscle itcrosses beneath the gustatory nerve, and is then placed above it. Vessels and Nerves.—The arteries supplying the submaxillary gland arebranches of the facial and lingual. Its veins follow the course of the nerves are derived from the submaxillary ganglion, through which it receivesfilaments from the chorda tympani of the facial and gustatory branch of the infe-rior maxillary, from the mylo-hyoid bra
