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.
Olfactory nerves. Also known as CN1, the olfactory nerve is the first of 12 cranial nerves located within the head. It relays sensory data to the brain, and it is responsible for the sense of smell.The nerve's olfactory receptors are located within the mucosa of the nasal cavity.Unlike many other nerves, CN1 does not possess two trunks.hile part of the nervous system, the CN1 does not join the brainstem. It and the optic nerve are the only cranial nerves for which this is true. CN1 is the shortest cranial nerve within the human head.
