The Glossopharyngeal Nerve.

The glossopharyngeal nerve is so intimately connected with the trigeminus, the facial, the pneumogastric and sympathetic nerves, that its function is not very well understood; hence very little is known as to lesions of this nerve. Difficulty in swallowing, and loss of sensation in the roof and walls of the pharynx, are most likely due to paralysis of the ninth nerve.
