Human anatomy, including structure and development and practical considerations . sels.—The arteries of the subhm^-ual ghmd are derived from the facial andthe suhliiiiiual brancli of the lingual. The veins are from the corresponding ones.The IvHip/iaties ijo to tlie submaxillary inlands. Nerves.—The inland receives filaments from the symi)athetic jilexus accompa-nying;- the facial artery, from the lingual nerve, and from the submaxillary j^anj;lion. The Sublingual Gland.—Tliis differs from the two precedinjj;^ glands in having-no capsule. It lies in loose areolar tissues on the mylo-hyoid muscle, at the frontpart of the sublingual space. Its weight is 3 or 4 gm. P2ach gland rests internallyagainst the genio-glossus, and anteriorly they touch one another. They are morereadily separated into lobes than the others. Testut regards them as aggregations ofseparate glands. The sublingual glands are covered by the mucous membrane of thefloor of the mouth, which they press upward into rounded swellings on either side Fig. 1345.

The lingual nerve and the submaxillary duct areon the inner side. The sublingual or Rivinis ducts vary in number from fourto twenty or more. They open for the most part in the floor of the mouth, butsome may join Whartons duct. Bartholins dud is an inconstant one, largerthan the others, that usually opens close to the outer side of Whartons duct, -whichit follows. Vessels.—The arteries are from the sublingual branch of the lingual and thesubmental branch of the facial, which latter sends minute twigs through the mylo-hyoidmuscle. The blood escapes into the ranine vein. The lymphatics run to the sub-maxillary nodes. Ne
