External Carotid Artery
The external carotid artery flows upward on the side of the head to branch into various structures in the neck, face, jaw, scalp, and base of the skull. The main vessels that originate from this artery are: (1) the superior thyroid artery, to the hyoid bone, larynx, and thyroid gland; (2) the lingual artery, to the tongue, muscles of the tongue, and salivary glands below the tongue; (3) the facial artery, to the pharynx (throat), palate, chin, lips, and nose; (4) the occipital artery, to the scalp on the back of the skull and various muscles in the neck; and (5) the posterior auricular artery, to the ear and scalp over the ear. The external carotid artery terminates by division into the maxillary and superficial temporal arteries.
