That is not true for facial artery ?

Correct answer: D. Is a branch of internal carotid artery

  • A. Main source of blood supply to palatine tonsil
  • B. Supplies branches to upper and lower lips
  • C. Conveys post ganglionic sympathetic fibers to submandibulr gland
  • D. Is a branch of internal carotid artery

Explanation

The facial artery is a branch of the external carotid artery, so the statement that it arises from the internal carotid is false. Its tonsillar branch, superior and inferior labial branches, and arterial plexus around the submandibular gland support the other statements.
