What Is a Jugulodigastric Lymph Node?
The jugulodigastric lymph node is a prominent lymph node in the deep lateral cervical group located behind the mandible, lying below the posterior belly of the digastric muscle and anterior to the internal jugular vein. The node receives lymphatic drainage from the pharynx, palatine tonsil, and tongue, according to medilexicon.com.
Lymph nodes are oval-shaped organs of the lymphatic system, distributed widely throughout the body and important to the function of the immune system, acting as filters for foreign pathogens and cancer cells, cites Healthline.com. Also called the subdigastric node, the jugulodigastric is the largest (and most frequently enlarged in reaction to infection or inflammation) of the 200–300 lymph nodes of the head and neck.
