A bolus injection (or similar substance) introduced into the tongue ultimately drains, via the lingual and/or facial veins, into which major venous structure?

The internal jugular vein
The external jugular vein only
The subclavian vein directly
The cavernous sinus

Show answer and explanation

Correct answer: A. The internal jugular vein

The tongue's venous drainage occurs via the lingual vein (sometimes joining the common facial vein), ultimately emptying into the internal jugular vein — the primary venous drainage pathway for most of the head and neck's deep structures.
