WebNeurophysiologic intraoperative monitoring (NIOM) of the glossopharyngeal and vagus nerves (CN IX and X) is often used during surgeries involving the lower brain stem. Although both of these nerves contain sensory, autonomic, and motor fibers, it is the motor fibers that are most amenable to NIOM. WebNerve supply Motor and sensory is from pharyngeal plexus (formed by branches from CN IX, X and sympathetic nerves) Motor fibres in the plexus is derived from cranial part of CN XI and carried by CN X and supplies all pharyngeal muscles except stylopharyngeus (CN IX) Sensory fibres in the plexus is derived from CN IX and supplies mucosa of all 3 ...
