The classification of the cervical lymph nodes is generally attributed to Henri Rouvière in his 1932 publication "Anatomie des Lymphatiques de l'Homme" [6] [7] Rouviere described the cervical lymph nodes as a collar which surrounded the upper aerodigestive tract, consisting of submental, facial, submandibular, parotid, mastoid, occipital and retropharyngeal nodes, together with two chains ...
The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp.

These lymph nodes are also known as glands or lymphoid tissue. If they detect something foreign passing through them, they enlarge. This is called lymphadenopathy or swollen glands.
A specific example would be the lateral portions of the eye's bulbar and palpebral conjunctiva as well as the skin adjacent to the ear within the temporal region. The efferents of these nodes pass to the superior deep cervical glands. The preauricular nodes glands will present with marked swelling in viral conjunctivitis. [1]
