1 sty 2018 · A glossopharyngeal nerve palsy is paralysis of the ninth cranial nerve. Clinical features include: loss of sensation - tested by the gag reflex. loss of taste sensation on the posterior 1/3 of the tongue. The competence of cranial nerves IX and X are usually tested with an overlapping set of tests, thus:
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.
Key points. Palsies of the third, fourth, and sixth cranial nerves are those most commonly encountered by the eye care provider. The causes of these palsies include trauma, vasculopathic, autoimmune, compression, inflammation, and infection.
25 paź 2020 · The glossopharyngeal nerve supplies sensory innervation to the oropharynx, and thus carries the afferent information for the gag reflex. When a foreign object touches the back of the mouth, this stimulates CNIX, beginning the reflex. The efferent nerve in this process is the vagus nerve, CNX.
15 mar 2019 · 59 Citations. 74 Altmetric. Metrics. Abstract. The human body has 12 pairs of cranial nerves that control motor and sensory functions of the head and neck. The anatomy of cranial nerves is complex and its knowledge is crucial to detect pathological alterations in case of nervous disorders.
Sixth nerve palsy causes convergent squint in the primary position with failure of abduction of the affected eye, producing horizontal diplopia that increases on gaze to the affected side and on looking into the distance (eFigure 7–69). It is an important sign of raised intracranial pressure and may also be due to trauma, neoplasms, brainstem ...
Anatomy. CN IX is innervated bilaterally and has sensory, parasympathetic, and motor components. 1 5 The sensory division receives general sensory fibers from the tonsils, pharynx, middle ear, and the posterior one-third of the tongue, as well as taste fibers from the posterior third of the tongue.
