The submandibular lymph nodes (submaxillary glands in older texts), three to six in number, are placed beneath the body of the mandible in the submaxillary triangle, and rest on the superficial surface of the submaxillary salivary gland.

One gland, the "middle gland of Stahr", which lies on the external maxillary artery as it turns over the mandible, is the most constant of the series; small lymph glands are sometimes found on the deep surface of the submaxillary salivary glands.

The "afferents" of the submaxillary glands drain the medial palpebral commissure, the cheek, the side of the nose, the upper lip, the lateral part of the lower lip, the gums, and the anterior part of the margin of the tongue.

"Efferent" vessels from the facial and submental glands also enter the submaxillary glands. Their efferent vessels pass to the superior deep cervical glands.
