Blood Vessels and Lymphatics of the Head & Neck

Overview

The head and neck contain complex vascular and lymphatic networks that support high metabolic demand and connect vital structures to the rest of the body. This section introduces the main arterial, venous and lymphatic pathways that supply and drain the brain, face, scalp and cervical region.

Key Structures

Topics include the major arteries of the head and neck, key venous drainage pathways including deep and superficial systems, and the lymphatic routes and node groups that serve cranial and cervical structures. Coverage also includes structures with unique relevance to this region, such as the dural venous sinuses and cavernous sinus.

Clinical Relevance and Learning Focus

Understanding head and neck vascular and lymphatic anatomy is crucial for assessing stroke patterns, venous congestion, lymphadenopathy and the spread of infection or malignancy. This knowledge supports safe interpretation of imaging, surgical planning and clinical examination across neurology, ENT, dentistry and emergency care.
