1. Reid described the function of the glossopharyngeal nerve and vagus nerve. 2. The glossopharyngeal nerve has parasympathetic fibers that innervate the parotid salivary gland. 3. The primary neural supply is from both the glossopharyngeal nerves . 4. The glossopharyngeal nerve innervates a third of the tongue including the circumvallate papillae. 5. The preganglionic parasympathetic fibres originate in the inferior salivatory nucleus of the glossopharyngeal nerve . 6. Signals from the carotid baroreceptors are sent via the glossopharyngeal nerve ( cranial nerve X ). 7. That is, a lot of taste information gets to the brain via the glossopharyngeal nerve . 8. The glossopharyngeal nerve as noted above is a mixed nerve consisting of both sensory and motor nerve fibers. 9. Rr . glomi carotici are the branches of vagus nerve but the origin of these fibers is glossopharyngeal nerve . 10. The cranial nerves that contain GVA fibers include the facial nerve, the glossopharyngeal nerve and the vagus nerve.
