The submandibular lymph nodes are a group of lymph nodes located in the submandibular triangle of the neck, along the angle and lower border of the mandible. They are bilateral structures, located superficial to the submandibular gland on either side.
The submandibular lymph nodes receive lymph from several structures along the path of the facial artery including: the region of the face inferior to the orbit, external nose, medial aspect of the cheek, upper lip and lateral parts of the lower lip. Additionally, they receive lymph drained from the teeth, gingivae (gums) and lateral portions of the body of the tongue.
Furthermore, the submandibular lymph nodes drain other regional lymph node groups including the submental, buccal and lingual groups of lymph nodes, giving off efferent vessels to the upper and lower deep cervical lymph nodes.
