| jugulodigastric lymph node | A prominent lymph node in the deep lateral cervical group lying below the digastric muscle and anterior to the internal jugular vein; it receives lymphatic drainage from the pharynx, palatine tonsil, and tongue. Synonym: nodus jugulodigastricus, jugulodigastric node, subdigastric node. (05 Mar 2000) |
| jugulo-omohyoid lymph node | A lymph node of the lateral deep cervical group that lies above the intermediate tendon of the omohyoid muscle and anterior to the internal jugular vein; it receives lymphatic drainage from the submental, submandibular, and deep anterior cervical nodes; its efferent vessels go to other deep lateral cervical nodes. Synonym: nodus jugulo-omohyoideus, jugulo-omohyoid node. (05 Mar 2000) |

| lymph node | <anatomy> Small bean-shaped organ made up of a loose meshwork of reticular tissue in which are enmeshed large numbers of lymphocytes, macrophages and accessory cells located along the lymphatic system. Recirculating lymphocytes leave the blood through the specialised high endothelial venules of the lymph node and pass through the node before being returned to the blood through the lymphatic system. Because the lymph nodes act as drainage points for tissue fluids, they are also regions in which foreign antigens present in the tissue fluid are most likely to begin to elicit an immune response. Nodes filter out bacteria or cancer cells that may travel through the lymphatic system. Synonym: lymph glands. (14 Oct 1997) |
| lymph node excision | Surgical excision of one or more lymph nodes. Its most common use is in cancer surgery. (12 Dec 1998) |
