The given picture demonstrates the digital palpation of the submental lymph nodes.

• Their afferents drain the central portions of the lower lip and floor of the mouth and the apex of the tongue.

• Their efferents pass partly to the submandibular lymph nodes and partly to a gland of the deep cervical group situated on the internal jugular vein at the level of the cricoid cartilage.
