Quain's elements of anatomy . It reaches from the frajnum Fig. 501.—View of the Right Sub- Fig. 501. MAXILLARY AND SUBLINGUAL GlANI>3 FROM THE INSIDE (Allen Thomson). Part of the right side of the jaw,divided from the left at the symphysis,remains; the tongue and its muscleshave been removed ; and the mucousmembrane of the right side has beendissected off and hooked upwards so as toexpose the sublingual glands ; s m, thelarger superficial part of the submaxillarygland; /, the facial artery passingthrough it; s m, deep portion prolongedon the inner side of the mylo-hyoidmuscle in k; s I, is placed below theanterior large part of the sublingualgland, with the duct of Bartholin partly shown ; s I, placed above the hinder small end of the gland, indicates one or two of theducts perforating the mucous membrane ; d, the papilla, at which the duct of Whartonopens in front behind the incisor teeth ; d, the commencement of the duct ; h, thehyoidbone ; n, the gustatory nerve ; close to it is the submaxillary ling-uje, in front, where it is in contact with the gland of the oppositeside, obliquely backwards and outwards for rather more than an inch anda half. On its inner side it rests on the genio-hyo-glossus ; below, itis supported by the mylo-hyoid muscle {mil), which is interposed betweenit and the main part of the submaxillary gland ; and it is here in closecontact with the Whartonian duct, with the accompanying deep portionof the last-named gland, and also with the lingual branch of the fifthnerve. The lobules of the subhngual gland are not so closely united togetheras those of the other salivary glands, and the ducts from many of themopen separately into the mouth, along the ridge which indicates theposition of the gland. These ducts, named ducts of E-ivini, are fromeight to twenty in number. Some of them open into the duct ofWharton. One, longer than the rest (which is occasionally derivedin part also from the submaxillary gland), runs along the Whartoni
