| 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. | Both the glossopharyngeal and vagus nerves carry sensory nerve fibres into the brain and central nervous system.
|
| 9. | The glossopharyngeal nerve as noted above is a mixed nerve consisting of both sensory and motor nerve fibers.
|
| 10. | This leads to release of the neurotransmitter dopamine in the glossopharyngeal and vagus afferente to the vasomotor area.
