Structure

Origin

The ascending palatine artery arises from the proximal facial artery (close to the facial artery's origin).[1]

Course

It passes superior-ward between the styloglossus muscle and stylopharyngeus muscle to reach the side of the pharynx.[1]

It ascends along the side of the pharynx between the superior pharyngeal constrictor and the medial pterygoid muscle[1] to near the base of the skull.[citation needed]

Near the levator veli palatini muscle, the artery splits into its two terminal branches.[1]

Branches

One terminal branch passes along the levator veli palatini muscle, winding around the superior border of the superior pharyngeal constrictor to provide arterial supply to the soft palate and anastomose with the greater palatine artery and its contralateral partner.[1]

The other terminal branch pierces the superior pharyngeal constrictor to provide arterial supply to the palatine tonsil and pharyngotympanic tube. It forms anastomoses with the tonsillar artery and ascending pharyngeal artery.[1]
