There are multiple connections with nuclei of neighboring brainstem nuclei for coordination of swallowing, gagging, and coughing. The other motor nuclei are the dorsal motor nucleus (X) and the inferior salivary nucleus (IX), located in the medulla dorsal and lateral to the twelfth nucleus.
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.
The glossopharyngeal nerve (/ ˌ ɡ l ɒ s oʊ f ə ˈ r ɪ n (d) ʒ i ə l,-ˌ f ær ən ˈ dʒ iː ə l / [1]), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, [2] is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve. Being a mixed ...
25 paź 2020 · The glossopharyngeal nerve, CN IX, is the ninth paired cranial nerve. In this article, we shall look at the anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches.
1 kwi 2023 · Glossopharyngeal (CN IX), vagus (CN X), and spinal accessory (CN XI) are intimately related, sharing some nuclei in the medulla and traveling closely together through the basal cistern, skull base, and carotid space.
The glossopharyngeal, vagus, spinal accessory, and hypoglossal nerves, also known as cranial nerves IX, X, XI, and XII, respectively, all combine to carry sensory, motor, and parasympathetic innervation to the pharynx, larynx, tongue, and many other regions.
7 lis 2022 · The glossopharyngeal nerve is the 9th cranial nerve (CN IX). It is 1 of the 4 cranial nerves with sensory, motor, and parasympathetic functions. It originates from the medulla oblongata and terminates in the pharynx.
