The submandibular lymph nodes (submaxillary glands in older texts) are lymph nodes beneath the body of the mandible in the submandibular triangle, and rest on the superficial surface of the submandibular gland.
One gland, the middle gland of Stahr, which lies on the facial 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 submandibular gland.
The afferents of the submandibular glands drain the medial canthus, 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 lymph vessels from the facial and submental lymph nodes also enter the submandibular glands. Their efferent vessels pass to the superior deep cervical lymph nodes.
AZ Sportivo Performance and AZSP Healing are Researching human body as a science from head to toe. Any pains, soreness, discomfort have reasons, root causes, we will find out and solve them as possible we can. Our approach is more neuromuscular and anatomical body structure than only muscles, more science and engineering to human body.
