- It receives taste sensory fibers from the posterior tongue
- It receives visceral sensory fibers from the carotid bodies, carotid sinus.
- It supplies parasympathetic fibers to the parotid gland
- It supplies motor fibers to stylopharyngeus muscle
- It contributes to the pharyngeal plexus.
Clinic
