GROSS ANATOMY

Detailed explanation-1: -The ascending pharyngeal artery normally arises from the posterior wall of the proximal external carotid artery trunk, cephalad, and close to the source of the occipital artery (1, 2). However, the ascending pharyngeal artery may arise from the proximal occipital artery.

Detailed explanation-2: -The external carotid artery (ECA) is one of the two terminal branches of the common carotid artery that has many branches that supplies the structures of the neck, face and head. The other terminal branch is the internal carotid (ICA), which is somewhat larger than the ECA, which supplies the intracranial structures.

Detailed explanation-3: -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.

Detailed explanation-4: -Superior thyroid artery. Ascending pharyngeal artery. Lingual artery. Facial artery. Occipital artery. Posterior auricular artery. Maxillary artery. Superficial temporal artery.
