What does the Palatoglossal arch do?
The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars). These pillars separate the oral cavity and the oropharynx — the muscle functions as an antagonist to the levator veli palatini muscle.
What happens if the hypoglossal nerve is damaged?
The hypoglossal nerve can be damaged at the hypoglossal nucleus (nuclear), above the hypoglossal nucleus (supranuclear), or interrupted at the motor axons (infranuclear). Such damage causes paralysis, fasciculations (as noted by a scalloped appearance of the tongue), and eventual atrophy of the tongue muscles.
What cranial nerve causes uvula deviation?
Central lesions of the vagus nerve can cause dysphagia, dysarthria and hoarseness; uvula deviation (towards the opposite side of the lesion); and transient parasympathetic effects.
How do you treat soft palate pain?
Getting plenty of rest (either in or out of bed) Taking ibuprofen (Advil, Motrin), acetaminophen (Tylenol) or aspirin (in adults only) to relieve throat pain. Drinking plenty of water to prevent dehydration. Gargling with warm salty water to ease throat pain.
What are palatoglossal folds?
palatoglossal arch one of a pair of ridges or folds of mucous membrane passing from the soft palate to the side of the tongue; it encloses the palatoglossus muscle and forms the anterior margin of the tonsillar fossa. Also demarcates the oral cavity from the isthmus of fauces.
Which of the following are symptoms of hypoglossal nerve damage?
When should I call a healthcare provider about problems with my hypoglossal nerve?
- Difficulty speaking (aphasia) or swallowing (dysphagia).
- Lack of sensation.
- Muscle weakness.
- Pain or a burning sensation.
- Uncoordinated movement.
What can mimic glossopharyngeal neuralgia?
Diseases of the eye, ears, nose, throat, and teeth may all mimic glossopharyngeal neuralgia or may coexist and confuse the diagnosis. Tumors of the hypopharynx, including the tonsillar fossa and piriform sinus, may mimic the pain of glossopharyngeal neuralgia, as will tumors at the cerebellopontine angle.
What are the symptoms of glossopharyngeal neuralgia?
Symptoms include severe pain in areas connected to the ninth cranial nerve:
- Back of the nose and throat (nasopharynx)
- Back of the tongue.
- Ear.
- Throat.
- Tonsil area.
- Voice box (larynx)
What is palatal palsy?
Introduction. Unilateral acquired isolated palatal (velopalatopharyngeal) paralysis is a clinical rarity usually seen in children. This isolated palatal palsy is the result of isolated involvement of the pharyngeal branch of the vagus nerve, which supplies motor fibers to muscles of the pharynx and soft palate.
