A

Palpable
Feels different on palpation depending on cause of lymphadenopathy
Submandibular lymphadenopathy often indicative of oral pathology, untreated may spread to cervical nodes

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
