<P> The glossopharyngeal nerve , known as the ninth cranial nerve ( CN IX ) , is a mixed nerve that carries afferent sensory and efferent motor information . It exits the brainstem out from the sides of the upper medulla , just rostral ( closer to the nose ) to the vagus nerve . The motor division of the glossopharyngeal nerve is derived from the basal plate of the embryonic medulla oblongata , while the sensory division originates from the cranial neural crest . </P>
