drainage of the tongue is very complex. There are three types of lymphatic
vessels. These are vessels in the margins of the tongue. They drain
lymphatic vessels to submental nodes, jugulo-omohyoid nodes and the
vessels: These are vessels line central portion of the tongue. They end in
the submandibular lymph nodes and the jugulo-diagastric and the
vessels: These run in the dorsum of the tongue. They end in the
jugulodigastric and the jugulo-omohyoid nodes.
the nodes drain into the deep cervical nodes from where they pass on to the
jugular trunk. The jugular trunk enters the thoracic duct on the left and the
right lymph duct on the right or the jugulosubclavian junction on the right.
