Taste Buds

tongue · five senses · how taste works · flavor detection

Clusters on your tongue. Taste buds are groups of taste receptor cells found on your tongue, the roof of your mouth, throat, cheeks, and even your windpipe. They sit on bumpy structures called papillae that you can actually see if you look in the mirror.

Five flavor families. Your taste buds detect five main types of flavors: salty, sour, bitter, sweet, and savory (called umami). Contrary to what many people think, all areas of your tongue can taste all five flavors, not just certain regions.

Saliva does the work. Food particles need to dissolve in your saliva before your taste buds can detect them. The dissolved food enters tiny openings called taste pores and touches the taste receptor cells.

Brain gets the signal. When your taste buds detect a flavor, the receptor cells send messages to your brain through special nerves. This happens so fast that you taste your food almost instantly.
