If you recall, CN VII is responsible for taste sensation in the anterior two-thirds of the tongue. Well, it's the glossopharyngeal nerve, also known as cranial nerve IX, that is the nerve responsible for the sensation of taste in the posterior one-third of the tongue. In addition, cranial nerve IX is a nerve that innervates one of the three major salivary glands, called the parotid gland.
The abducens nerve carries motor impulses to the lateral rectus eye muscle which moves the eye laterally causing abduction of the eye. Which cranial nerves carry gustatory (taste) information? CN VII (Facial), CN IX (Glossopharyngeal) and CN X (Vagus). Which cranial nerve is the longest? CN X (Vagus) which reaches from the medulla to the digestive and urinary organs. What two cranial nerves carry sensory information about blood pressure to the brain? CN IX (Glossopharyngeal) and CN X (Vagus). Which cranial nerve is responsible for pupillary constriction? CN III (Oculomotor).
