Tongue Anatomy: Papillae and Taste Perception

This lecture covers the histological characteristics of the tongue, including the microanatomy of salivary glands, muscles, and different segments of the digestive tract. It focuses on the structure and function of lingual papillae, such as filiform, fungiform, circumvallate, and foliate papillae, and their association with taste buds. The lecture also discusses the sensory perception of taste, detailing the transduction mechanisms for sweet, bitter, umami, salty, and sour tastes, as well as the distribution of taste receptors on the tongue. Additionally, it explores the lingual tonsil, nerve supply to the tongue, and the complex innervation of teeth and supporting tissues.
