glossopharyngeal nerve
the ninth cranial nerve; it originates as several rootlets from the medulla oblongata, between the olive and the inferior cerebellar peduncle, and supplies the carotid sinus, mucous membrane, and muscles of the pharynx, soft palate,
and posterior third of the tongue, and the taste buds in the posterior third of the tongue. It provides for reflex control
of the heart, and is also responsible for the swallowing reflex, for stimulating secretions of the parotid glands, and for the sense of taste in the posterior third of the tongue.
