Olfactory neurons in the olfactory mucosa are stimulated by chemical odorants and their axons form the olfactory nerves (CN I), whereas gustatory cells respond to dissolved chemicals and send sensory impulses via the facial (CN VII), glossopharyngeal (CN IV), and vagus (CN X) nerves to the thalamus. Taste buds are bud-shaped structures made up of gustatory (taste sensing) cells - anywhere from 10-50 cells per bud. Despite this fact, no structural . A. Lingual papilla B. When taste receptor cells are stimulated, they send signals through three cranial nerves to taste regions in the brainstem — the facial, glossopharyngeal, and vagus nerves. The central gustatory pathways are part of the brain circuits upon which rest the decision to ingest or reject a food. The five chemical structures that your taste cells can detect are: The buds are . Some stimuli interact with receptors to generate second messengers, whereas in other instances, the taste . Gustatory receptor cells are found in the taste buds of fungiform, foliate, and circumvallate papillae located mainly on the tongue. Small hair-like extensions from these receptors serve as the sites for odor . Some papillae help create friction between the tongue and food. The five taste modalities (sweet, sour, salty, bitter, and umami) are perceived in different regions of the tongue. Neurotransmitters from the gustatory cells can activate sensory neurons in the facial, glossopharyngeal, and vagus cranial nerves. There are four types of papillae, based on their appearance ( Figure 15.1.1 ): circumvallate, foliate, filiform, and fungiform. These impulses get routed through the thalamus, which relays sensory information to other brain regions. infundibulum. The gustatory cortex is the area of the brain that allows people to perceive tastes, such as this ice cream sundae. Within the structure of the papillae are taste buds that contain specialized gustatory receptor cells for the transduction of taste stimuli.
