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.
Origin and central course. The branchial motor component originates from the nucleus ambiguus in the reticular formation of the rostral medulla. Fibers leaving the nucleus ambiguus travel anteriorly and laterally to exit the medulla, along with the other components of CN IX, between the olive and the inferior cerebellar peduncle.

11 kwi 2019 · Cranial nerve IX is the glossopharyngeal nerve, important for parasympathetic, motor and sensory innervation of the tongue, pharynx and larynx. Here, we break down the different anatomical structures contributing to the glossopharyngeal nerve and discuss its clinical relevance.
Lateral to CN VII (cerebellopontine angle) Located in the internal acoustic canal. Mediates sensation of sound, rotation, and gravity (essential for balance and movement). More specifically, the vestibular branch carries impulses for equilibrium and the cochlear branch carries impulses for hearing. IX Glossopharyngeal: Both sensory and motor ...
There are many branches, which transmit a combination of sensory, motor and parasympathetic fibres. The other cranial nerves are the vestibulocochlear, the glossopharyngeal, the vagus, spinal accessory and hypoglossal nerves.
3 lis 2023 · Glossopharyngeal nerve (CN IX) Cranial nerve 9 is another multimodal nerve. It originates from the brainstem and leaves the skull through the jugular foramen. It enables swallowing, salivation, and taste sensation, as well as visceral and general sensation in the oral cavity.
