• Each circumvallate papilla has a central depression called a "taste bud trench" that contains taste buds.
• The taste buds on circumvallate papillae are responsible for detecting bitter tastes.
• Circumvallate papillae are surrounded by a raised ridge of tissue that helps protect the taste buds from damage.
• They are larger than other types of papillae, such as fungiform and foliate papillae.
• Some people have a larger number of circumvallate papillae than others, which may affect their ability to taste bitter flavors.
• Circumvallate papillae play an important role in the sense of taste and the perception of flavors.
