CN VII, or the facial nerve, is responsible for taste in the anterior two-thirds of the tongue. CN IX (glossopharyngeal) and CN X (vagus) are responsible for taste in the posterior one-third of the tongue and into the pharynx. If you think about swallowing a pill and it gets stuck in your vallecula you continue to taste the horrible bitter taste and it will not go away. That is because CN IX and X are still sending the sensory input of the taste. We are able taste into the pharynx.
