Anatomy study note · Head and neck

Deep cervical lymph nodes

The terminal group of head and neck nodes: a vertical chain along the internal jugular vein in the carotid sheath, from the skull base to the root of the neck. All head and neck lymph ends here.

Key points

• Along the internal jugular vein; terminal group.
• Jugulodigastric = tonsil; jugulo-omohyoid = tongue.
• → jugular trunks → thoracic duct / right lymphatic duct.
• Lymph sacs → lymph nodes (except cisterna chyli).
• Thoracic duct → left IJV–subclavian junction.
• Node: cortex (B-cell nodules) / paracortex (T cells, HEVs) / medulla.
