Origin
The pharyngeal branches of the glossopharyngeal nerve originate roughly on the posterior surface of the stylopharyngeus muscle as they split off the main trunk of the glossopharyngeal nerve.
Course
From their origins, the pharyngeal branches of the glossopharyngeal nerve run medially around the backside of the middle pharyngeal constrictor muscle.
Branches
The pharyngeal branches of the glossopharyngeal nerve coalesce with fibers from the vagus nerve and the sympathetic trunk to form the pharyngeal plexus.
Supplied Structures
The pharyngeal branches of the glossopharyngeal nerve are sensory. They convey general visceral sensory fibers from the oropharynx and surrounding mucosal membranes.
