The Glossopharyngeal nerve if damaged can have several effects on the human body.

Glossopharyngeal nerve for the posterior 1/3 of the tongue.

Glossopharyngeal neuralgia, a rare disorder, usually begins after age 40 and occurs more often in men.

There are a number of functions of the glossopharyngeal nerve:

The glossopharyngeal nerve runs on the lateral side of this muscle, and crosses over it to reach the tongue.

The primary neural supply is from both the vagus and glossopharyngeal nerves.

The third pharyngeal arch is innervated by glossopharyngeal nerve.

The glossopharyngeal nerve also aids in tasting, swallowing and salivary secretions.

Injury to the glossopharyngeal nerve can result in dysgeusia.

The glossopharyngeal nerve is mostly sensory.

The clinical tests to see if the Glossopharyngeal nerve has been damaged includes testing the gag reflex of the mouth.

These peripheral processes have cell their cell body in either the superior or inferior glossopharyngeal ganglion.

It branch of the glossopharyngeal nerve, runs downwards anterior to the internal carotid artery.

The stylopharyngeal branch of glossopharyngeal nerve is distributed to the Stylopharyngeus.

GN may also occur in combination with trigeminal or glossopharyngeal neuralgia.

Glossopharyngeal ganglion is a ganglion associated with cranial nerve IX.

It is one of the components of the glossopharyngeal nerve (cranial nerve IX).

The tissues in the throat rub on the styloid process during the act of swallowing with resulting pain along the glossopharyngeal nerve.

The stylopharyngeus and other structures from the third brachial arch are all innervated by the glossopharyngeal nerve.

The glossopharyngeal nerve continues past the palatine tonsil and innervates the tongue to provide general and taste sensation.

These cells are shown to synapse upon the chorda tympani and glossopharyngeal nerves to send their signals to the brain.

Parasympathetic component of the glossopharyngeal nerve that innervates the ipsilateral parotid gland.

Other paraganglia along the cervical and thoracic branches of the vagus and glossopharyngeal nerves.

The glossopharyngeal nerve is the ninth (IX) of twelve pairs of cranial nerves (24 nerves total).

The integrity of the glossopharyngeal nerve may be evaluated by testing the patient's general sensation and that of taste on the posterior third of the tongue.
