Submaxillary Gland (glandula submaxillaris).The submaxillary gland (Fig. 1024) is irregular in form and about the size of a walnut. A considerable part of it is situated in the submaxillary triangle, reaching forward to the anterior belly of the Digastricus and backward to the stylomandibular ligament, which intervenes between it and the parotid gland. Above, it extends under cover of the body of the mandible; below, it usually overlaps the intermediate tendon of the Digastricus and the insertion of the Stylohyoideus, while from its deep surface a tongue-like deep process extends forward above the Mylohyoideus muscle.
| Its superficial surface consists of an upper and a lower part. The upper part is directed outward, and lies partly against the submaxillary depression on the inner surface of the body of the mandible, and partly on the Pterygoideus internus. The lower part is directed downward and outward, and is covered by the skin, superficial fascia, Platysma, and deep cervical fascia; it is crossed by the anterior facial vein and by filaments of the facial nerve; in contact with it, near the mandible, are the submaxillary lymph glands.|

| The deep surface is in relation with the Mylohyoideus, Hyoglossus, Styloglossus, Stylohyoideus, and posterior belly of the Digastricus; in contact with it are the mylohyoid nerve and the mylohyoid and submental vessels.|
| The external maxillary artery is imbedded in a groove in the posterior border of the gland.|
| The deep process of the gland extends forward between the Mylohyoideus below and externally, and the Hyoglossus and Styloglossus internally; above it is the lingual nerve and submaxillary ganglion; below it the hypoglossal nerve and its accompanying vein.|
| The submaxillary duct (ductus submaxillaris; Whartons duct) is about 5 cm. long, and its wall is much thinner than that of the parotid duct. It begins by numerous
