Touch has many receptors in the skin that detect things like texture, temperature, and pain. Smell receptors in the nose detect chemicals dissolved in mucus that allow us to perceive odors. Taste buds on the tongue contain receptors that send messages to the brain about the basic tastes of sweet, salty, bitter, and sour.
