Tongue is a mucosa-invested moveable muscular structure that has two regions. Root anchors tongue into the hyoid bone while body is freely moving in the oral cavity. The dorsum of the tongue is covered by masticatory mucosa sporting lingual papillae. The core of the tongue is composed of two groups of skeletal muscle, intrinsic group and the extrinsic group. The four types of lingual papillae are outgrowths of the mucosa of the dorsal surface. These types are filiform papillae, fungiform papillae, foliate papillae, and circumvallate papillae.
