This short video segment from IdahoPTV's D4K shows a diagram of the parts of the tongue. It explains how papillae, taste buds and tiny hairs work to help you decide if food is sweet, sour, bitter or salty.

JOAN CARTAN-HANSEN: Your tongue is covered with thousands of tiny bumps called papiliae. Inside those bumps on the back part of the roof of your mouth and in the very back of your throat are 10,000 taste buds. The tiny cells have little hairs. Dissolved food particles seep into the hairs and the taste buds sense whether the food is sweet, sour, bitter or salt. That information is sent to your brain and then you decide if the food is good or bad.
CHILD: Did you know most of your sense of taste comes from your sense of smell?
CHILD: So let's share.
CHILDREN: HE-E-E-Y!
