The Facial Nerve The facial nerve is complicated. Not only does it control most muscles of the face; this nerve also transmits taste signals from the front of the tongue, conveys parasympathetic fibers that make the eyes tear and mouth salivate, and is responsible for a little bit of sensation around the ear.
Taste. As shown to the right, each taste bud consists of a cluster of sensory cells forming synapses with neurons with long axons. These project to the medulla in one of three cranial nerves (VII,IX,X). The sensory cells release glutamate when stimulated by their corresponding taste.Scattered over the tongue, there are five classical types of taste buds: salt, sweet, sour, bitter, and umami. Salt and sweet are self-explanatory.The bitter respond to various plant alkaloids, sour to acid (such as might be found in spoiled foods), and the umami to glutamate and some related substances.aste.
