Online photos, illustrations, slide shows and videos of lymph nodes in the neck are available from medical experts such as MedicineNet, Healthline and WebMD. Lymph nodes are located throughout the body, including the neck, and are part of the overall lymph system, which carries fluids, waste and nutrients, explains WebMD.
The lymph nodes are a prominent part of the body's immune system, and swollen nodes may therefore indicate an infection, explains WebMD. Types of lymph nodes in the neck and upper chest area include cervical and supraclavicular nodes, depicted in a detailed illustration on WebMD's eMedicineHealth website. It is important to consult with a physician if swollen lymph glands persist for two weeks or more, if they are hard or growing, or are accompanied by weight loss, fever, night sweats or fatigue.
