HA2: Tongue, H&E

Digest02o
At low magnification, the taste buds (HA2, tb) of the circumvallate papillae look somewhat similar to dermal papillae, but they are specialized epithelial cells not CT. Draining into the moat of the circumvallate papilla, there is a duct (d) of the serous von Ebner’s glands (HA2, E). Also, note that there are occasional lymph patches (arrowheads) in the lamina propria.
