Tongue and soft-palate hemispherical cell clusters {taste bud}| hold cells {taste receptor cell} that have tip microvilli. Adult tongue has 10,000 taste buds, but babies have more. Taste buds last one week, fade, and then new ones grow.
Taste-bud cells have tips with projections {microvillus} {microvilli} that extend into taste pore.
Tongue has four bump types {papilla}| {papillae}.
Papillae {circumvallate papilla} can be largest, be before tonsils, be large circular mounds with depressed circumference, and have three to five taste buds (on tongue rear sides).
Papillae {filiform papilla} can be smallest, be most, be down top middle, and have no taste buds.
Papillae {foliate papilla} can be medium-size, be at back sides, be tissue folds at tongue rear and outsides, and have taste buds.
Papillae {fungiform papilla} can be next smallest, be on tongue broad part, be one-millimeter-size mushroom shapes at tongue tip and edges, and have six taste buds each.
