The follicular papillae of the tongue are generally symmetrical and crepuscular. 1. The anterior 2/3 of the tongue is covered with four types of lingual papillae, i.e., filiform papillae, fungiform papillae, contour papillae, and lobulated papillae. The lobulated papillae are located at the posterior part of the lateral margin of the tongue, near the pharynx, and are 5-8 longitudinal folds. Contain taste buds, responsible for the perception of flavor (gustation), and are elongated on the scanning electron microscope. Generally symmetrical. 2. The lobulated papillae are rich in lymphoid tissue such as lingual tonsils. When inflammation of the lobular papilla occurs, it is red, swollen and congested, and the patient often has obvious irritation pain or discomfort, which produces a fear of cancer. If there is any discomfort in the lobulated papillae of the tongue, it is recommended to consult a hospital as soon as possible to identify the cause of the disease and further treatment.
