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.
22 maj 2017 · Pharyngeal branches (GSA): Together with the branches of the vagus nerve, these form the pharyngeal plexus (see CN X). Stylopharyngeal branch (SVE): It innervates the stylopharyngeus muscle and parts of the superior constrictor pharyngeal muscle.
7 lis 2022 · Its branches consist of tympanic, tonsillar, stylopharyngeal, carotid sinus nerve, branches to the tongue, lingual branches, and a communicating branch to cranial nerve X (vagus nerve). See Image. The Glossopharyngeal Nerve.
Pharyngeal branches (rr. pharyngei) provide sensory innervation to the mucous membrane of the pharynx, tonsils, and soft palate. These branches create the anastomosis with the branches of the vagus nerve as well as with the branches of the sympathetic trunk to form the pharyngeal plexus.
