LINGUAL TONSIL

Plate 9.163 Lingual Tonsil

Human, 10% formalin, H. & E., 55 x.

 

The posterior one third of the human tongue has a relatively uncomplicated non-keratinized stratified squamous epithelium. The lamina propria, however, contains lymphoid nodules and innumerable non- aggregated white blood cells (lymphocytes and plasma cells).

The lingual tonsil, along with the palatine and pharyngeal (adenoids) tonsils, forms a massive ring of immunocompetent cells guarding the entrance to the respiratory and digestive systems.
