There are a number of functions of the glossopharyngeal nerve: It receives general sensory fibers (ventral trigeminothalamic tract) from the tonsils, the pharynx, the middle ear and the posterior 1/3 of the tongue. It receives special sensory fibers (taste) from the posterior one-third of the tongue. The glossopharyngeal nerve (n. glossopharyngeus) is a mixed cranial nerve containing both sensory and motor components. It provides sensitivity-related and sensory innervation to the palate and the throat, and also to the back of the tongue, especially with respect to the sensation of bitter tastes. By serving the carotid sinus, the glossopharyngeal nerve provides for reflex control of the heart.

The glossopharyngeal nerve provides motor function to the stylopharyngeus muscle. Located in the pharynx, which is the portion of your throat behind the nose and mouth, this muscle is involved in swallowing. It shortens and widens the pharynx and lifts the larynx (commonly called the voice box) when you swallow. 3
The case offered opportunity for physiologic study of the functions of the ninth and glossopharyngeal neuralgia: [ noo͡-ral´jah ] pain in a nerve or along the course of one or more nerves, usually consisting of a sharp, spasmlike pain that may recur at intervals. It is caused by inflammation of or injury to a nerve or group of nerves.

The glossopharyngeal nerve supplies sensory innervation to the oropharynx, and thus carries the afferent information for the gag reflex. When a foreign object touches the back of the mouth, this stimulates CNIX, beginning the reflex.

Glossopharyngeal neuralgia consists of recurring attacks of severe pain in the back of the throat, the area near the tonsils, the back of the tongue, part of the ear, and/or the area under the back of the jaw.

General visceral efferent : this component of the glossopharyngeal nerve transmits the parasympathetic information to the parotid salivary gland. 2019-04-11 Kranialnerver är nerver som ansluter direkt till hjärnan eller hjärnstammen. Människan har 12 par kranialnerver som har olika funktion. Kranialnerverna förmedlar dels sensoriska signaler till hjärnan, dels motoriska signaler från hjärnan. Function: Receives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus.
It shortens and widens the pharynx and lifts the larynx (commonly called the voice box) when you swallow. 3 The glossopharyngeal nerve supplies sensory innervation to the oropharynx, and thus carries the afferent information for the gag reflex. When a foreign object touches the back of the mouth, this stimulates CNIX, beginning the reflex. The efferent nerve in this process is the vagus nerve, CNX. The glossopharyngeal nerve has many functions, including receiving various forms of sensory fibers from parts of the tongue, carotid body, the tonsils, the pharynx, and the middle ear. Glossopharyngeal nerve function The glossopharyngeal nerve is a mixed nerve that contains both motor and sensory fibers. It originates from the medulla oblongata, where the four of its nuclei are located. Those nuclei give rise to the functionally diverse neuronal fibers that are involved in the motor and sensory functions of this nerve.
