Document Summary
Physical stimuli for the sense of taste are chemical substances that are soluble. Gustatory receptors are clusters of taste cells found in the taste buds that line the trenches around tiny bumps on the tongue. Four primary tastes: sweet, sour, bitter, and salty. Perceptions of taste quality appear to depend on the complex patterns of neural activity initiated by taste receptors. Some basic taste preferences appear to be innate and automatically regulated by physiological mechanisms. People vary considerably in their sensitivity to certain tastes. Variations in sensitivity mean that when two people taste the same food, they will not necessarily have the same sensory experience. Supertasters generally have better health habits than non-tasters. Women more likely to be supertasters than men. Flavor is a combination of taste, smell, and the tactile sensation of food in one"s mouth. Humans usually characterized as being relatively insensitive to smell. Physical stimuli are chemical substances volatile ones that are carried in the air.
