Similarly, the term lymphadenitis refers to inflammation of a lymph node, but often it is used as a synonym of lymphadenopathy. Cervical lymphadenopathy is a sign or a symptom, not a diagnosis.
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck.. Some sources state simply that they lie along the external jugular vein, [1] while other sources state that they are only adjacent to the external jugular vein in the posterior triangle, and they are adjacent to the anterior jugular vein in the anterior triangle.
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 superficial nodes are supplied by lymphatics that are present throughout the arm, but are particularly rich on the palm and flexor aspects of the digits. Superficial lymph nodes of the arm: Supratrochlear nodes: Situated above the medial epicondyle of the humerus , medial to the basilic vein , they drain the C7 and C8 dermatomes .
The anterior cervical lymph nodes are a group of nodes found on the anterior part of the neck, in front of the sternocleidomastoid muscle. These can be grouped into a deep and superficial group . The superficial group drain the superficial surfaces of the anterior neck.

The most common cause of enlargement of the submental lymph nodes are infections (including viral infections (mononucleosis, Epstein-Barr virus infection, and cytomegaloviral infections), toxoplasmosis, and dental infections (e.g. periodontitis)).
The superficial lateral cervical lymph nodes are found along the course of the external jugular vein, between the inferior aspect of the parotid gland and the supraclavicular nodes. The nodes are intercalated along the course of the vessels draining the parotid nodes and the infraauricular nodes.
