![]() ![]() Key points about the lymph nodes of the headīuccinator, nasolabial, malar, mandibular nodesĭirection of flow: Facial nodes → submandibular nodes → jugulodigastric node → inferior deep lateral cervical nodes → supraclavicular nodes → jugular trunk → thoracic duct (left) or right lymphatic duct This ring of lymph nodes drain regions of the nose, cheeks, ear, scalp and chin to the superficial or deep lymph nodes of the neck. The pericervical lymphatic circle is located at the junction between the head and neck and consists of the occipital, mastoid, superficial and deep parotid, submandibular and submental lymph nodes. This group of lymph nodes drains regions of the face to the submandibular lymph nodes via efferent vessels. The facial lymph nodes are located along the facial vein and consist of the buccinator, nasolabial, malar and mandibular lymph nodes. Its efferent vessels drain to either the superior deep lateral cervical nodes, submandibular and/or submental nodes. The lingual lymph nodes are located at the center of the pericervical lymphatic circle and function in draining the tongue. Lymph nodes of the head are generally divided into three separate groups: the lingual lymph nodes, facial lymph nodes and a group of five lymph nodes which make up the pericervical lymphatic circle. Efferent lymph vessels of the lingual lymph nodes drain to the jugulodigastric lymph node of the superior deep lateral cervical nodes, as well as the submandibular and submental lymph nodes. This group of visceral nodes are found along the genioglossus muscle and function to drain lymph from the tongue. These lymph nodes travel along the facial vein and are made up of the buccinator, nasolabial, malar and mandibular lymph nodes.Īt the center of the pericervical lymphatic circle are the last group of lymph nodes of the head: the lingual lymph nodes. ![]() As the name suggests, this group of lymph nodes receive lymph from regions of the face and drain to the submandibular lymph nodes via efferent vessels. They drain to the superficial or deep lymph nodes of the neck via efferent vessels.Ībove the pericervical lymphatic circle is another group of lymph nodes known as the facial lymph nodes. These nodes present in a ring-like arrangement and function to receive lymph from regions of the nose, cheeks, ear, scalp and chin. These are the occipital, mastoid, superficial and deep parotid, submandibular and submental lymph nodes. Nodi lymphatici occipitales, Lymphonodi occipitalesĪt the junction between the head and neck are five groups of lymph nodes which form the pericerivcal lymphatic circle, also called the pericervical collar. Pharyngeal lymphoid ring (pharyngeal, lingual, palatine and tubal tonsils)Īxillary nodes (lateral, anterior, posterior, central, apical) Pericervical lymphatic circle (occipital, mastoid, parotid (superficial and deep), submandibular and submental lymph nodes)ĭeep anterior cervical nodes (prelaryngeal, thyroid, pretracheal and paratracheal nodes)ĭeep lateral cervical nodes (superior and inferior deep lateral cervical nodes) Lymph nodes of the head, neck and upper limb receive, filter and transport lymphatic fluid from surrounding lymph nodes and viscera back into the bloodstreamįacial nodes (buccinator, nasolabial, malar and mandibular nodes) Key points about the lymph nodes of the head, neck and upper limb This article will discuss the anatomy and function of the lymph nodes of the head, neck and arm. Superficial and deep afferent and efferent lymphatic vessels drain lymph to and from these nodes to ultimately reach the subclavian lymphatic trunk. Lymph nodes of the upper limb include the cubital, axillary, infraclavicular and interpectoral lymph nodes. These lymph nodes receive lymphatic drainage from the lymph nodes of the head and drain into either the thoracic duct on the left or the right lymphatic duct. The lymph nodes of the neck are typically organized into superficial and deep nodes which are further classified into anterior and lateral cervical lymph nodes. There are three main groups of lymph nodes within the head: the lingual lymph nodes, facial lymph nodes and a group of lymph nodes which form a ring at the junction between the head and neck known as the pericervical lymphatic circle. Lymph nodes of the head filter lymph from regions of the head, face and scalp and typically drain to the superficial and deep lymph nodes of the neck. Lymph nodes and vessels of the head, neck and upper limb are generally divided into superficial and deep groups. Lymph nodes of the head, neck and upper limb function to receive, filter and transport lymphatic fluid from surrounding tissues and viscera back into the bloodstream via the thoracic duct, right lymphatic duct and/or subclavian lymphatic trunk. ![]()
