Lymph Nodes in the Head and Neck: Anatomy and Function #3324664 (License: Personal Use)

This anatomical illustration depicts the distribution of lymph nodes along the cervical, submandibular, and retropharyngeal regions of the head and neck. The nodes are shown as green clusters embedded in connective tissue, draining lymph from mucosal surfaces and skin. Their strategic positioning supports early detection of pathogens and plays a vital role in adaptive immunity.
