What is the Glossopharyngeal Nerve? 10 hilariously insightful foreign words. The glossopharyngeal nerve is also called the ninth cranial nerve. Cranial nerves are vital nerves that arise from the brain that help the brain control muscles, process the five senses, and control glands in the body.

Vagus Nerve Stimulation Vagus Nerve Stimulation. The vagus nerve is one of 12 pairs of cranial nerves that originate in the brain and is part of the autonomic nervous system, which controls involuntary body functions. The nerve passes through the neck as it travels between the chest and abdomen and the lower part of the brain.

What Does the Vagus Nerve Control? The vagus nerve, which runs from the brainstem to the organs of the chest and abdomen, sends and receives messages to control the functioning of the digestive system, heart, lungs, and some glands. The longest nerve in the cranium, it has multiple branches that influence many organs.

The 12 Cranial Nerves of the Human Body Functions. Each of the 12 cranial nerves has a specific function that helps the brain control the actions of the body. 1  The olfactory nerve is involved in the sense of smell. 2  This nerve has access to the cerebral cortex, but does not pass through the thalamus like other cranial nerves.he 12 cranial nerves control some of the most important functions of the body. In addition, these nerves allow us to feel pain, indicating when there is a serious problem that requires medical intervention.

The Glossopharyngeal Nerve (CN IX) Overview. Embryologically, the glossopharyngeal nerve is associated with the derivatives of the third pharyngeal arch. Sensory: Innervates the oropharynx, carotid body and sinus, posterior 1/3 of the tongue, middle ear cavity and Eustachian tube.ig 1.2 – Path of the parasympathetic fibres to the parotid gland. The glossopharyngeal nerve provides parasympathetic innervation to the parotid gland. These fibres originate in the inferior salivatory nucleus of CN IX. These fibres travel with the tympanic nerve to the middle ear.

Chapter 5: Facial sensations & movements The motor portion of. this nerve supplies the muscles of the face and scalp: buccinator, platysma and so on, along with. motor control to the submandibular, sublingual and lacrimal glands. The sensory portion of this. nerve carries sensory information for taste from the anterior 2/3 of the tongue and the palate. Lesions of the facial nerve cause facial paralysis that is usually unilateral. There is also a loss of. taste sensation in the anterior 2/3 of the tongue and decreased salivation.

What Cranial Nerves Make Up the Parasympathetic System? Of all the parasympathetic cranial nerves, the vagus nerve, which contains about 80 percent of all parasympathetic fibers in the body, is the most important.ranial Nerve IX, the Glossopharyngeal Nerve. The glossopharyngeal nerve has a number of functions related to taste and eating. Parasympathetic fibers in this nerve control the parotid glands, the largest of the salivary glands. Salivation is necessary for eating, a peace time function.

Nerves of the Head and Neck The muscles of the head and neck are also controlled by various cranial nerves including the facial nerve (facial expression) and accessory nerve (head and neck movements). Wandering through the neck and torso, the vagus nerve communicates vital information from the brain to the heart and intestines.

The Glossopharyngeal Nerve (CN IX) 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.ig 1.2 – Path of the parasympathetic fibres to the parotid gland. The glossopharyngeal nerve provides parasympathetic innervation to the parotid gland. These fibres originate in the inferior salivatory nucleus of CN IX. These fibres travel with the tympanic nerve to the middle ear.

Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality Let's review what the cranial nerves do one more time. The facial nerve, also known as cranial nerve VII, is the most important nerve controlling muscles of facial expression. It is responsible for the sensation of taste in the anterior two-thirds of your mouth.

The Names, Functions, and Locations of Cranial Nerves Cranial Nerves. The cranial nerves are nerves that arise from the brain and exit the skull through holes (cranial foramina) at its base rather than through the spinal cord. Peripheral nervous system connections with various organs and structures of the body are established through cranial nerves and spinal nerves. While some cranial nerves contain only sensory neurons, most cranial nerves and all spinal nerves contain both motor and sensory neurons. Function Cranial nerves are responsible for the control of a number of functions in the body. Some of these functions include directing sense and motor impulses, equilibrium control, eye movement and vision, hearing, respiration, swallowing, smelling, facial sensation, and tasting.

Glossopharyngeal neuralgia (throat pain) Glossopharyngeal neuralgia is an irritation of the ninth cranial nerve causing extreme pain in the back of the throat, tongue and ear. Attacks of intense, electric shock-like pain can occur without warning or can be triggered by swallowing. Although the exact cause is not known, a blood vessel is often found compressing the nerve. It can r neck cancer. Medications may initially relieve the pain, but surgery is often needed for long-term relief. What is glossopharyngeal neuralgia? Neuralgia is severe pain caused by injury or damage to a nerve. The glossopharyngeal nerve is the ninth (IX) cranial nerve, which arises from the brainstem inside the skull. It supplies sensation to the back of the throat and tongue and portions of

- What is it and why should you care? The vagus nerve is the primary communicator of the brain to the parasympathetic nervous system, responsible for the relaxation response, and to the sympathetic nervous system, the fight, flight, or freeze response.

- The cranial nerves carry taste information into the brain to a part of the brain stem called the nucleus of the solitary tract. From the nucleus of the solitary tract, taste information goes to the thalamus and then to the cerebral cortex.ike information for smell, taste information also goes to the limbic system (hypothalamus and amygdala). Another cranial nerve (the trigeminal nerve, V) also innervates the tongue, but is not used for taste. Rather, the trigeminal nerve carries information related to touch, pressure, temperature and pain.

Attacks of intense, electric shock-like pain can occur without warning or can be triggered by swallowing.igure 1. The glossopharyngeal nerve (9th cranial nerve) is related to the back of the tongue and throat. It has branches to the ear, tonsil, and carotid body. Glossopharyngeal pain can be similar to trigeminal neuralgia – and misdiagnosed.

Chapter 7 - Lower cranial nerve function Chapter 7 - Lower cranial nerve function. The lower cranial nerves are involved in pharyngeal and laryngeal function as well as in movements of the neck and tongue. Damage usually manifests as problems with speech and swallowing.These nerves arise from the medulla and, in the case of the accessory nerve (CN XI), the spinal cord.These nerves are commonly affected by conditions damaging the medulla, but bilateral damage to corticobulbar connections can create motor problems that affect tongue and pharynx movement and speech.oth the glossopharyngeal and vagus nerves (CN IX and X) have taste and somatic sensory functions that are not routinely examined. However, the taste function in the glossopharyngeal nerve (CN IX) can be examined if there is suspicion of damage to the nerve (vagus nerve taste function cannot be tested).

Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality This is mainly thanks in part to the fact that the facial nerve also conveys the sensation of taste from the anterior two-thirds of your tongue. And, even before you put the steak in your mouth, there is saliva inside of your mouth that will help in the process of digestion. Two out of the three of the most important salivary glands are innervated by the facial nerve. These glands are known as the submandibular and sublingual salivary glands. Combined, these two glands produce the vast majority of the saliva in your mouth.

The Glossopharyngeal Nerve (CN IX) The glossopharyngeal nerve provides parasympathetic innervation to the parotid gland. These fibres originate in the inferior salivatory nucleus of CN IX. These fibres travel with the tympanic nerve to the middle ear. From the ear, the fibres continue as the lesser petrosal nerve, before synapsing at the otic ganglion.
