Anatomical terms of neuroanatomy

The glossopharyngeal nerve (/ˌɡlɒsfəˈrɪn(d)ʒiəl, -ˌfærənˈəl/[1]), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX,[2] 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 motor information. The motor division of the glossopharyngeal nerve is derived from the basal plate of the embryonic medulla oblongata, whereas the sensory division originates from the cranial neural crest.
