The submental lymph node is located right below the chin. This specific placement is part of the lymphatic system, which plays a crucial role in immune responses and the drainage of lymphatic fluid from various parts of the body. The submental lymph nodes receive drainage primarily from the lower lip, floor of the mouth, and the tip of the tongue, making their location significant for assessing conditions related to these areas, including infections or malignancies.

In contrast, the other options refer to different anatomical sites that do not correspond with the submental lymph node's position. The hollow of the clavicle pertains to the supraclavicular lymph nodes, while the junction between the back of the head and the neck would be associated with the posterior cervical lymph nodes. Lastly, behind the ears relates to the postauricular or mastoid lymph nodes. Understanding these distinctions helps reinforce the anatomical knowledge pertinent to lymphatic drainage pathways and related clinical assessments.
