The palatine tonsil is an egg-shaped mass, which bulges into the oral cavity. The oral surface is covered by stratified squamous epithelium.
The epithelium passes down into the crypts in the substance of tonsil. Between the crypts the masses of dense.
lymphoid tissue arranged in folds containing the individuals follicles.
At intervals, between folds of lymphatic tissue; connective tissue septa pass up form the basal layer of connective tissue, which separates the tonsil form the subjacent structures.
Below this basal layer of connective tissue, lie bundles of skeletal muscle fibres.
Round the periphery on the luminal edge are mucous gland – tonsilar glands.
