Which branch of the glossopharyngeal nerve is sensory to both the carotid sinus and carotid body?
Branch to the carotid sinus
Which branch of the glossopharyngeal nerve senses changes in blood pressure and blood gases?
Branch to the carotid sinus
Which branch of the glossopharyngeal nerve unites with branches from the vagus and sympathetic trunk to form the pharyngeal plexus?
Pharyngeal branch
Which branch of the glossopharyngeal nerve is sensory to the pharynx?
Pharyngeal branch
Which branch of the glossopharyngeal nerve senses pain in acute pharyngitis (sore throat) and is the afferent limb of the gag reflex?

Lingual branch
What is the longest cranial nerve?
Vagus (X)
What does “vagus” mean?
Wanderer
Which cranial nerve emerges from the medulla oblongata and exits the skull through the jugular foramen along with the glossopharyngeal and accessory nerves?
Vagus
What are the two vagus nerve ganglia in the neck?

Which branch of the vagus nerve is associated with cervicogenic headaches?
Meningeal
Which branch of the vagus nerve supplies the dura mater with sensory innervation?
Meningeal
Which branches of the vagus nerve arise from the superior ganglion?
Meningeal and auricular
Which branch of the vagus nerve senses pain in otitis externa (swimmer’s ear)?

Auricular
Which branch of the vagus nerve is the chief motor nerve to the muscles of the pharynx and soft palate?
Pharyngeal
Where do most of the fibers that make up the pharyngeal branch of the vagus nerve originate from?
