Explain the Structure of Tongue

The tongue is a muscular organ. It is covered with a mucous membrane. The tongue is attached by its base to the hyoid bone and by a fold of its mucous membrane covering called the frenulum. The superior surface of the tongue is covered by stratified squamous epithelium with little projections called papillae (small nodules of tissue). Papillae contain the taste buds (small and large) and the nerve endings of the sense of taste. There are three types of papillae.
