What are swollen lymph nodes in the neck

Lymph nodes are important immune organs in the body. They are the places where antigen stimulation is received and immune responses are produced. They have filtering, proliferation and immune functions. Normal superficial lymph nodes in the human body are very small, with a diameter of less than 0.5 cm. The surface is smooth and soft, with no adhesion to the surrounding tissues and no tenderness. When the body is invaded by pathogenic factors, information is transmitted to the lymph nodes, and lymphocytes produce lymphokines and antibodies to effectively kill the pathogenic factors. The result of the "struggle" between the two is the reactive proliferation of lymphocytes and tissue cells in the lymph nodes, causing the lymph nodes to swell.

reason

There are three causes of swollen lymph nodes in the neck: infection, tumor and other factors. Infectious factors: Bacterial - bacterial infection of teeth, tonsils, face or scalp, tuberculosis, syphilis, cat scratch disease, Lyme disease; Viral - herpetic stomatitis, infectious mononucleosis, HIV infection (AIDS); Parasitic - toxoplasmosis; Unknown cause: mucocutaneous lymph node syndrome (Kawasaki disease), subacute necrotizing lymphadenitis (Kikuchi disease).
