Extrapyramidal contributions to cranial nerves IX and X are poorly understood, but can be significant causes of laryngeal and pharyngeal dysfunction. Movement disorders of the larynx include Parkinson’s, essential tremor, and spasmodic dysphonia.

7 lis 2022 · Idiopathic glossopharyngeal neuralgia is caused by compression of cranial nerve IX by a vessel or dysfunction of the central pons. In contrast, secondary glossopharyngeal neuralgia can result from trauma, neoplasm, infection of the throat, surgery, or malformations.
Multiple small lesions in the cortex and/or brainstem interrupt the corticobulbar supply to the motor nuclei of various cranial nerves. Etiologies include multiple sclerosis, hypertensive lacunes, and other causes of bihemispheric disease.
22 maj 2017 · The glossopharyngeal nerve, or the ninth cranial nerve (CN IX) arises from the lateral aspect of the upper medulla. It is important in several pharyngeal and laryngeal functions. It also subserves important autoregulatory functions such as maintaining blood pressure and monitoring blood pH.
Vagus nerve funtion (craniel nerve X) can be compromised in schizophrenia, bulimia, obesity, and major depression. A cervical lesion to the nerve roots of the spinal accessory nerve (craniel nerve XI) can cause a cervical dystonia, which sometimes is misdiagnosed as a dyskinesia related to neuroleptic use.
The glossopharyngeal nerve (CN IX) supplies organs, muscles and other structures in your mouth and throat. It helps you taste food and sense pain in your throat. CN IX can become damaged due to cancer, complications from medical procedures and more.
Disorders affecting the lower cranial nerves – V (trigeminal), VII (facial), IX (glossopharyngeal), X (vagus), XI (accessory) and XII (hypoglossal) – are discussed in the first part of this chapter. The clinical neuroanatomy of each nerve is described in detail, as are disorders – often in the form of lesions – for each nerve.
