Document Summary
We have 2 senses for detecting chemicals in our environment: taste and smell and together they are referred to as the chemosenses. Chemosense: one of the two sense modalities (gustation and olfaction) that detect the presence of particular molecules present in the environment. Gustation: the sense of taste-> it is the simplest of the sense modalities- taste flavor flavor includes odor, texture, touch, taste. The flavors of foods diminish when you have a cold not because your taste buds are not operating, but because mucus congestion makes it difficult for odor. Laden air to reach your receptors for the sense of smell without odours, onions and apples taste the same. Tongue has a corrugated appearance: creases and bumps. Papilla: a small bump on the tongue that contains a group of taste buds. Taste bud: a small organ on the tongue that contains a group of gustatory receptor cells.
