Often the largest lymph node in the neck, the jugulodigastric node is located just below the inferior margin of the mandible, close to the insertion of masseter muscle. This node receives lymph from the tongue, pharynx, and palatine tonsils. For this reason, the jugulodigastric lymph node typically becomes swollen during tonsil infections (Földi et al., 2012).
