Above vocal cords - infrahyoid nodes directly to deep cervical chain Below vocal cords - prelaryngeal and pretracheal nodes directly to deep cervical chain Trachea - pretracheal and paratracheal nodes directly to deep cervical chain
46
What is the drainage of the pharynx and oesophagus
Retropharyngeal/paratracheal nodes directly to deep cervical nodes
47
What is the clinical correlation of lymph nodes
Palpable Feels different on palpation depending on cause of lymphadenopathy Submandibular lymphadenopathy often indicative of oral pathology, untreated may spread to cervical nodes
48
What is virchows node
Is supraclavicular node located in left supraclavicular fossa Receives drainage from abdominal cavity Enlarged is referred to as troisiers sign and indicates presence of cancer in abdomen that has spread through lymph vessels
