Via small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with taste receptors. b. multipolar neuron | Quizlet Explanations Question Gustatory cells are a. bipolar neurons. The little bumps, or papillae, on your tongue contain taste buds (gustatory sense) and are direct chemoreceptors because they must make direct contact with the food item to taste it. Every gustatory receptor cell has a spindly protrusion called a gustatory hair. Therefore, rather than working as the receptive field of peripheral taste receptor cells, the central gustatory pathways seem to operate as a multisensory system dedicated to evaluate the biological significance of intra . Taste receptor cells are to the gustatory system as:A. hair cells are to the auditory system. Gustatory receptor cells are found in the taste buds of fungiform, foliate, and circumvallate papillae located mainly on the tongue.

The facial nerve connects to taste buds in the anterior third of . Binding may occur directly, or by way of proteins in the mucus (called odorant binding proteins) that sequester the odorant and shuttle it to the receptor. Once the gustatory cells are activated by the taste molecules, they release neurotransmitters onto the dendrites of sensory neurons. There are four types of papillae, based on their appearance ( Figure 15.1.1 ): circumvallate, foliate, filiform, and fungiform.
