11 kwi 2019 · When examining CN IX, it is important to test the glossopharyngeal nerve. One of the more accessible terminal branches of this nerve is the tonsillar branch, which supplies sensory innervation to the oropharynx.
The glossopharyngeal nerve has five distinct general functions: Branchial motor (special visceral efferent) – supplies the stylopharyngeus muscle. Visceral motor (general visceral efferent) – provides parasympathetic innervation of the parotid gland via the otic ganglion.
CN I. The first test is for the olfactory nerve. Smell is tested in each nostril separately by placing stimuli under one nostril and occluding the opposing nostril. The stimuli used should be non-irritating and identifiable. Some example stimuli include cinnamon, cloves, and toothpaste.
