Which papillae are few in number, associated with most taste buds, and linked with Von Ebner's glands?

The circumvallate papillae are indeed characterized by being few in number, typically numbering between 8 to 12, and are located at the back of the tongue. They are associated with numerous taste buds, which are responsible for the sensation of taste. Each circumvallate papilla is surrounded by a trench, which helps to trap food particles and enhance the taste sensation.

Additionally, circumvallate papillae are linked with Von Ebner's glands, which are serous glands located beneath the papillae. These glands secrete a watery fluid that helps to wash away food debris and provides a conducive environment for taste reception. The fluid secreted by Von Ebner's glands contains enzymes that assist in breaking down food substances, thus enhancing the ability to taste.

In contrast, the other types of papillae have different characteristics. Fungiform papillae, although they contain taste buds, are more numerous and primarily located on the anterior part of the tongue. Foliate papillae are located on the sides of the tongue and also contain taste buds, but they are less prominent in humans compared to other animals. Filiform papillae provide texture to the tongue and are involved in mechanical processes rather than taste perception, as they do
