Glossopharyngeal nerve: Structure, Functions & Clinical significance

The glossopharyngeal nerve (/ˌɡlɒsoʊfəˈrɪn(d)ʒiəl, -ˌfærənˈdʒiːəl/), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve. Being a mixed nerve (sensorimotor), it carries afferent sensory and efferent…
