It may be a branch of the occipital (livini, 13%; Quain, 14%; Poynter, 15%), internal carotid (Poynter,6%), or even the common carotid or its bifurcation.
It is occasionally doubled or tripled.
It may give rise to the ascending palatine or superior laryngeal.
A palatine branch of this artery may be larger than usual and supplies the soft palate, taking the place of the inferior palatine branch of the facial, which in such cases is small. The palatine branch divides into two, anterior and posterior, both of which anastomose across the midline with the vessels of the opposite side.
This artery varies greatly as to its place of origin from the external carotid artery or bifurcation of the common carotid artery (~65-80%), it may be a branch of the occipital artery (20 to 14%), or it may arise from the common carotid artery (9 to 7%).
The artery is usually the second branch of the external carotid artery, though it may be the first.
This artery may give rise to esophageal arteries.
