At the superior border of the styloglossus muscle, the tonsillar branch pierces through the superior pharyngeal constrictor muscle to reach the inferior pole of the palatine tonsil.
Branches
There are no named branches.
Supplied Structures
The tonsillar branch of the facial artery provides the main blood supply to the palatine tonsils and superior pharyngeal constrictor muscle.
