The lingual vein, accompanying the lingual artery, drains into which vessel?
Show answer and explanation
Correct answer: A. Internal jugular vein
- A. Correct. The lingual vein drains to the internal jugular vein, either directly or via a common facial-lingual trunk. This is a route by which sublingual infection can reach the cranial sinuses.
- B. The pterygoid plexus drains the infratemporal region and communicates with the cavernous sinus — not the primary lingual drainage.
- C. The lingual vein may join a common trunk with the facial vein, but the ultimate destination is the internal jugular.
- D. The external jugular drains superficial face and scalp (posterior auricular + retromandibular).
