circumvallate papilla

Circumvallate papillae are among the structures on the tongue that house taste buds. These papillae are large, circular, and have a wall around them, hence the name "circumvallate". They are located on the back of the tongue and are particularly sensitive to bitter tastes.1

The tongue itself is a muscular organ on the floor of the mouth, crucial for tasting, chewing, swallowing, and, in humans, speech. Its surface is covered in papillae, which contain taste buds. These taste buds are clusters of receptor cells that detect chemical stimuli from food, enabling the perception of tastes like salty, sweet, sour, bitter, and umami.23
