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.
Cranial Nerve VII, the Facial Nerve. The facial nerve has both sensory and motor nerve endings throughout the face, which are responsible for sensation and muscle movement. Parasympathetic fibers in the facial nerve control a number of glands that secrete fluid or mucus. One such gland is the lacrimal gland, which makes tears to keep the eyes moist.
