if someone has neck cancer, where might lymph drain and potentially spread?
drains to jugulo-omohyoid node
what is the thoracic duct
transports lymph and drains into venous system
what does the thoracic duct drain into

would you lose function of swallowing if you damaged the hypoglossal?
no but it would be very difficult
