Respuesta :
Chemical senses
Explanation:
Olfaction and gustation are called chemical senses because they have sensory receptors that respond to molecules in the food we eat or in the air we breathe
- Olfaction is odor detection, the olfactory receptors are located in the olfactory epithelium, a dime-sized area at the top of each nasal cavity
- An epithelium is a layer of cells, so the olfactory epithelium is a layer of cells devoted to the sense of smell
- The receptors feed directly into a part of the brain called the olfactory bulb
- Gustation is usually called the sense of taste, despite the fact that olfaction dominates our ability to taste foods and liquids
- Taste cells are gathered together in taste buds on the tongue, and taste buds are hidden in bumps on the tongue called papillae
- Olfaction and gustation are are stimulated by chemicals, the molecules of which interact with receptors to produce a generator potential (olfaction) or receptor potential (gustation)
