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.

Introduction [edit]. The Gustatory System or sense of taste allows us to perceive different flavors from substances like food, drinks, medicine etc. Molecules that we taste or tastants are sensed by cells in our mouth, which send information to the brain.eurons in the gustatory cortex respond to the five main tastes. Taste cells synapse with primary sensory axons of the mentioned cranial nerves. The central axons of these neurons in the respective cranial nerve ganglia project to rostral and lateral regions of the nucleus of the solitary tract in the medulla.
