Which of the following papillae contains Von Ebner’s glands?

Among the various types of papillae on the tongue, only the circumvallate papillae contain Von Ebner’s glands.

Von Ebner’s glands are serous glands located in the connective tissue cores of circumvallate papillae. These glands secrete lingual lipase, an enzyme that begins the digestion of dietary fats in the oral cavity. The other types of papillae on the tongue, such as filiform, fungiform, and foliate papillae, do not contain Von Ebner’s glands.
