What are the lymph nodes located immediately inferior to the chin called?

The lymph nodes located immediately inferior to the chin are called submental lymph nodes. These nodes are part of the lymphatic system and are important for filtering lymph fluid from the tissues in the area of the chin and floor of the mouth. They play a crucial role in the immune response, particularly in detecting and managing infections or malignancies in the head and neck region. Their location beneath the mental symphysis of the mandible makes them distinctive, as they lie just above the hyoid bone and below the chin, in the submental space.

The other types of lymph nodes mentioned serve different anatomical regions. For example, the submandibular lymph nodes are located beneath the mandible, while the supraclavicular and suprasternal nodes are situated in the neck and upper chest regions, respectively, and are not immediately beneath the chin. Understanding the anatomy and positioning of these lymph nodes is crucial for healthcare professionals, especially in the context of diagnosing and treating head and neck conditions.
