Which Glands Rinse the Trenches Around Taste Papillae?
Von Ebner glands beneath circumvallate papillae send watery serous secretion through ducts into the surrounding trench. This local fluid helps clear taste-bearing surfaces; the duct opens into the trench lumen, not directly into a taste bud.

What the illustration shows
English medical poster on navy blue showing a peach-colored cutaway of a circumvallate papilla. Blue trenches flank the raised papilla, and gold oval taste buds sit within its lateral epithelial walls. Deeper coral gland clusters connect to a blue-filled duct that opens into the trench. Labels identify the papilla, trench, taste bud, gland duct and Von Ebner gland. A lower magnified inset shows the duct opening into the trench beside, but separate from, a taste bud. Gold AllHumanBody.com branding and full slogan appear below.
How to interpret this poster
- Duct width, cell sizes, blue fluid and bubble-like highlights are teaching conventions, not actual secretion color, pressure jets or measured flow.
- No exclusive bitter-taste zone, every-papilla generalization, regeneration claim or human taste-recovery promise.
- Glands lie deeper than epithelial taste buds; the drawing is not a literal histology section.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
