Summary

- course: vertically with internal carotid artery (ICA) and to the side of the pharynx
-
supply: base of skull;
anastamosisanastomosis with anterior and posterior cerebral circulations - termination: base of skull
Gross anatomy
Origin
It arises from the back part of the external carotid, near the carotid bifurcation and ascends vertically between the internal carotid and the side of the pharynx, to the under surface of the base of the skull, lying on the longus capitis.
Variant anatomy
Very rarely, the ascending pharyngeal artery can arise directly from the internal carotid artery 4.
