![]() ![]() Sending a throat culture to the laboratory and getting it analyzed, is a sure way of identifying its cause. Strep throat is one of the leading throat infections caused by bacteria. It is most likely that a patient suffering from swollen lymph nodes has contracted some form of throat infection due to a viral or bacterial attack. He may also feel swollen lymph nodes behind the ear, because of an ear infection. A patient with infected lymph nodes may suffer from fever. However, the swelling can also be due to various conditions such as common cold, upper respiratory infection, mononucleosis, sore throat, strep throat, viral infection, tuberculosis, tonsillitis, rubella, HIV, AIDS, toxoplasmosis, peritonsillar abscess, epiglottitis, sinus infection, ear infection, cancers (larynx cancer, lymphoma, Hodgkin’s disease, leukemia). Pain is generally associated with infectious diseases. There are chances of these entities overcoming the immune cells and falling prey to them. Within the lymph nodes, the lymphocytes such as T-cells and B-cells try to eliminate harmful foreign entities if they are present in the lymph. The neck also houses some other groups of deep cervical nodes such as lateral jugular, anterior jugular, jugulodigastric and inferior deep cervical nodes such as jugulo-omohyoid. These also serves as the receiving nodes for the lymph from the superior deep cervical glands along with that from the skin and muscles of the neck. The latter group of nodes, flush the lymph from the back of the scalp and neck, superficial pectoral region, part of the arm and superior surface of the liver. The former group carries lymph from the occipital portion of the head, scalp, the auricula, the back of the neck, thyroid gland, the larynx, nasal part of the pharynx, esophagus, trachea, nasal cavities, palate and tongue. They are grouped as the superior deep cervical glands and the inferior deep cervical glands. Deep Cervical Lymph NodesĪ string of nodes that stretch from the base of the skull to the neckline along the carotid sheath, pharynx, esophagus, and trachea are collectively called deep cervical lymph nodes. Enlargement of this node may point to presence of lymphoma, any of the different intra-abdominal malignancies, breast cancer or an infection of the arm. Its task makes it vulnerable to the various kinds of malignancies. It is the junction where incoming lymph is introduced back into the venous circulation through the left subclavian vein. A lymph node just above the left clavicle is known as Virchow’s node and is the most important node in the transit of lymph from the abdomen. Supraclavicular lymph nodes oversee transport of the lymph from the thoracic cavity and abdomen. These are present in the hollow of the clavicle (collarbone) and close to where it joins sternum. The lymph is drained to submandibular lymph nodes and to deep cervical group. ![]() These are located immediately below the chin and are responsible for flushing lymph from the tip of the tongue, middle of the lower lip and the central incisors. In case of children, nature takes special care of awarding them with larger nodes. Lymph nodes in the neck, in cooperation with the rest of the nodes present in the body, filters the lymph in order to combat pathogens such as, bacteria and viruses present in the lymph. The lymph is carried from interstitial spaces via capillaries, ducts and nodes, back to the blood circulatory system. It gets collected in spaces known as interstitial spaces which exist between the body tissues. It is a one-way network of lymph capillaries, lymph ducts, lymph nodes and special organs such as the spleen, tonsils, adenoids, appendix, thymus glands and bone marrow.ĭuring blood circulation, a small part of it seeps through the walls of the blood vessels in the form of clear, colorless liquid called lymph. This system is an important part of the body’s defense mechanism against foreign bodies. They are distributed throughout the body, except the nervous system. These are a part of the lymphatic system. Concentration of these nodes is higher in the groin, under the armpits and on both sides of the neck. (2017).The lymph nodes are bean-shaped organs that contain lymphocytes, a type of white blood cells.
