    • foliate papillae
    • -

    • •The foliate papillae are normal bilateral structures on the most posterior lateral surface of the tongue. They may be small nodules or vertical folds and grooves. They are composed of lymphoid tissue and may contain taste buds. In smokers, they may get very red and exaggerated. It is an
