A diagram of lymph nodes in the neck area is available on the eMedicineHealth and the University of California, San Diego websites. A 360-degree map of the various lymph nodes in the neck is also featured at Healthline.
The lymph nodes are primary components of the lymphatic system, which mainly functions in the protection against foreign invaders that could potentially harm the human body. These nodes are specially prominent in the neck, along the jaw, under the armpits and in the groin area.
The diagram at eMedicineHealth depicts the superficial lymph nodes in the area, which include the cervical lymph nodes. The image at the University of California, San Diego, shows cervical, tonsillar, submental and submandibular nodes. Users at Healthline can see the name of a particular node by hovering their mouse over the node.
