What is the glossopharyngeal nerve responsible for?
Table of Contents
swallowing
The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing.
What cranial nerve does Parkinson’s affect?
Background: The vagus nerve has been suggested to represent one major route of disease progression in Parkinson’s disease (PD).
What is the innervation of the glossopharyngeal nerve?
Containing both sensory and motor components, the glossopharyngeal nerve provides somatic motor innervation to the stylopharyngeus muscle, visceral motor innervation to the parotid gland, and carries afferent sensory fibers from the posterior third of the tongue, pharynx, and tympanic cavity.
What type of doctor treats glossopharyngeal neuralgia?
If the pain requires further evaluation, a neurologist or a neurosurgeon may be recommended. The diagnosis of neuralgia is made after carefully assessing the patient’s symptoms. If glossopharyngeal neuralgia is suspected, the doctor will attempt to trigger an episode by touching the back of the throat with a swab.
What type of doctor treats Glossopharyngeal neuralgia?
What are the symptoms of Glossopharyngeal neuralgia?
Symptoms of glossopharyngeal neuralgia may include severe pain in areas connected to the ninth cranial nerve, which are: Nasopharynx, or back of the nose and throat. Back of the tongue. Ear….The pain can be triggered by:
- Chewing.
- Coughing.
- Laughing.
- Speaking.
- Swallowing.
How are the eyes mouth and Laryngopharynx affected by Parkinson’s?
These findings suggest that pharyngeal sensory nerves are directly affected by pathologic processes in PD. These abnormalities may decrease pharyngeal sensation, thereby impairing swallowing and airway protective reflexes and contributing to dysphagia and aspiration.
What are the nuclei of glossopharyngeal nerve?
This nerve has altogether 4 nuclei that are located in the medulla oblongata: The ambiguous nucleus. The inferior salivary nucleus. The spinal nucleus of the trigeminal nerve.
What is the glossopharyngeal nerve?
The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat.
What is the function of the glossopharyngeal nucleus?
Besides the glossopharyngeal nerve, this nucleus is common for the vagus nerve and the accessory nerve . This nucleus contains neurons that provide motor innervation to several muscles of the soft palate, the pharynx, the larynx and the upper part of the esophagus. The axons of these neurons are distributed to the cranial nerves IX, X and XI.
What is the afferent pathway of the glossopharyngeal nerve?
Afferent Pathway. The pathway for the afferent fibers of the glossopharyngeal nerve is the following (from the initiation in the periphery to the termination in the brain): The tympanic plexus supplies the auditory canal and the pharyngeal orifice.
What is the function of the pharyngeal nerve?
It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing. What are nerves?
