Neuralgia Glossopharyngeal Anatomy
To better understand glossopharyngeal neuralgia, it helps to understand the anatomy of the cranial nerves.
The glossopharyngeal nerve is cranial nerve IX (9).
It is a nerve that supplies sensation to the back of the throat and tongue. It also supplies motor function to the pharynx and the larynx.
