WebThe gustatory pathways can differentiate between a larger number of individual stimuli than the olfactory pathway. The olfactory pathway travels via the thalamus, while the gustatory pathway does not. The olfactory pathway uses chemoreceptors while the gustatory pathway uses photoreceptors. WebIn terrestrial vertebrates, including humans, taste receptors are confined to the oral cavity. They are most abundant on the tongue but also occur on the palate and epiglottis and in the upper part of the esophagus. The taste receptor cells, with which incoming chemicals interact to produce electrical signals, occur in groups of 50–150. Each of these groups …
